Reply to Objection 9: A severe punishment is inflicted not only on account of the gravity of a fault, but also for other reasons. First, on account of the greatness of the sin, because a greater sin, other things being equal, deserves a greater punishment. Secondly, on account of a habitual sin, since men are not easily cured of habitual sin except by severe punishments. Thirdly, on account of a great desire for or a great pleasure in the sin: for men are not easily deterred from such sins unless they be severely punished. Fourthly, on account of the facility of committing a sin and of concealing it: for such like sins, when discovered, should be more severely punished in order to deter others from committing them.
Again, with regard to the greatness of a sin, four degrees may be observed, even in respect of one single deed. The first is when a sin is committed unwillingly; because then, if the sin be altogether involuntary, man is altogether excused from punishment; for it is written ( Dt. 22:25, seqq.) that a damsel who suffers violence in a field is not guilty of death, because "she cried, and there was no man to help her." But if a man sinned in any way voluntarily, and yet through weakness, as for instance when a man sins from passion, the sin is diminished: and the punishment, according to true judgment, should be diminished also; unless perchance the common weal requires that the sin be severely punished in order to deter others from committing such sins, as stated above. The second degree is when a man sins through ignorance: and then he was held to be guilty to a certain extent, on account of his negligence in acquiring knowledge: yet he was not punished by the judges but expiated his sin by sacrifices. Hence it is written ( Lev. 4:2 ): "The soul that sinneth through ignorance," etc. This is, however, to be taken as applying to ignorance of fact; and not to ignorance of the Divine precept, which all were bound to know. The third degree was when a man sinned from pride, i.e. through deliberate choice or malice: and then he was punished according to the greatness of the sin [*Cf. Dt. 25:2 ]. The fourth degree was when a man sinned from stubbornness or obstinacy: and then he was to be utterly cut off as a rebel and a destroyer of the commandment of the Law [*Cf. Num. 15:30 , 31 ].
Accordingly we must say that, in appointing the punishment for theft, the Law considered what would be likely to happen most frequently ( Ex. 22:1-9 ): wherefore, as regards theft of other things which can easily be safeguarded from a thief, the thief restored only twice their value. But sheep cannot be easily safeguarded from a thief, because they graze in the fields: wherefore it happened more frequently that sheep were stolen in the fields. Consequently the Law inflicted a heavier penalty, by ordering four sheep to be restored for the theft of one. As to cattle, they were yet more difficult to safeguard, because they are kept in the fields, and do not graze in flocks as sheep do; wherefore a yet more heavy penalty was inflicted in their regard, so that five oxen were to be restored for one ox. And this I say, unless perchance the animal itself were discovered in the thief's possession: because in that case he had to restore only twice the number, as in the case of other thefts: for there was reason to presume that he intended to restore the animal, since he kept it alive. Again, we might say, according to a gloss, that "a cow is useful in five ways: it may be used for sacrifice, for ploughing, for food, for milk, and its hide is employed for various purposes": and therefore for one cow five had to be restored. But the sheep was useful in four ways: "for sacrifice, for meat, for milk, and for its wool." The unruly son was slain, not because he ate and drank: but on account of his stubbornness and rebellion, which was always punished by death, as stated above. As to the man who gathered sticks on the sabbath, he was stoned as a breaker of the Law, which commanded the sabbath to be observed, to testify the belief in the newness of the world, as stated above (Q[100], A[5]): wherefore he was slain as an unbeliever.
Reply to Objection 10: The Old Law inflicted the death penalty for the more grievous crimes, viz. for those which are committed against God, and for murder, for stealing a man, irreverence towards one's parents, adultery and incest. In the case of thief of other things it inflicted punishment by indemnification: while in the case of blows and mutilation it authorized punishment by retaliation; and likewise for the sin of bearing false witness. In other faults of less degree it prescribed the punishment of stripes or of public disgrace.
The punishment of slavery was prescribed by the Law in two cases. First, in the case of a slave who was unwilling to avail himself of the privilege granted by the Law, whereby he was free to depart in the seventh year of remission: wherefore he was punished by remaining a slave for ever. Secondly, in the case of a thief, who had not wherewith to make restitution, as stated in Ex. 22:3.
The punishment of absolute exile was not prescribed by the Law: because God was worshipped by that people alone, whereas all other nations were given to idolatry: wherefore if any man were exiled from that people absolutely, he would be in danger of falling into idolatry. For this reason it is related ( 1 Kings 26:19) that David said to Saul: "They are cursed in the sight of the Lord, who have case me out this day, that I should not dwell in the inheritance of the Lord, saying: Go, serve strange gods." There was, however, a restricted sort of exile: for it is written in Dt. 19:4 [*Cf. Num. 35:25 ] that "he that striketh [Vulg.: 'killeth'] his neighbor ignorantly, and is proved to have had no hatred against him, shall flee to one of the cities" of refuge and "abide there until the death of the high-priest." For then it became lawful for him to return home, because when the whole people thus suffered a loss they forgot their private quarrels, so that the next of kin of the slain were not so eager to kill the slayer.
Reply to Objection 11: Dumb animals were ordered to be slain, not on account of any fault of theirs; but as a punishment to their owners, who had not safeguarded their beasts from these offenses. Hence the owner was more severely punished if his ox had butted anyone "yesterday or the day before" (in which case steps might have been taken to butting suddenly). Or again, the animal was slain in detestation of the sin; and lest men should be horrified at the sight thereof.
Reply to Objection 12: The literal reason for this commandment, as Rabbi Moses declares (Doct. Perplex. iii), was because the slayer was frequently from the nearest city: wherefore the slaying of the calf was a means of investigating the hidden murder. This was brought about in three ways. In the first place the elders of the city swore that they had taken every measure for safeguarding the roads. Secondly, the owner of the heifer was indemnified for the slaying of his beast, and if the murder was previously discovered, the beast was not slain. Thirdly, the place, where the heifer was slain, remained uncultivated. Wherefore, in order to avoid this twofold loss, the men of the city would readily make known the murderer, if they knew who he was: and it would seldom happen but that some word or sign would escape about the matter. Or again, this was done in order to frighten people, in detestation of murder. Because the slaying of a heifer, which is a useful animal and full of strength, especially before it has been put under the yoke, signified that whoever committed murder, however useful and strong he might be, was to forfeit his life; and that, by a cruel death, which was implied by the striking off of its head; and that the murderer, as vile and abject, was to be cut off from the fellowship of men, which was betokened by the fact that the heifer after being slain was left to rot in a rough and uncultivated place.
Mystically, the heifer taken from the herd signifies the flesh of Christ; which had not drawn a yoke, since it had done no sin; nor did it plough the ground, i.e. it never knew the stain of revolt. The fact of the heifer being killed in an uncultivated valley signified the despised death of Christ, whereby all sins are washed away, and the devil is shown to be the arch-murderer.
Whether the judicial precepts regarding foreigners were framed in a suitable manner?
Objection 1: It would seem that the judicial precepts regarding foreigners were not suitably framed. For Peter said ( Acts 10:34 , 35 ): "In very deed I perceive that God is not a respecter of persons, but in every nation, he that feareth Him and worketh justice is acceptable to Him." But those who are acceptable to God should not be excluded from the Church of God. Therefore it is unsuitably commanded ( Dt. 23:3 ) that "the Ammonite and the Moabite, even after the tenth generation, shall not enter into the church of the Lord for ever": whereas, on the other hand, it is prescribed ( Dt. 23:7 ) to be observed with regard to certain other nations: "Thou shalt not abhor the Edomite, because he is thy brother; nor the Egyptian because thou wast a stranger in his land."
Objection 2: Further, we do not deserve to be punished for those things which are not in our power. But it is not in man's power to be an eunuch, or born of a prostitute. Therefore it is unsuitably commanded ( Deut. 23:1 , 2 ) that "an eunuch and one born of a prostitute shalt not enter into the church of the Lord."
Objection 3: Further, the Old Law mercifully forbade strangers to be molested: for it is written ( Ex. 22:21 ): "Thou shalt not molest a stranger, nor afflict him; for yourselves also were strangers in the land of Egypt": and ( Ex. 23:9 ): "Thou shalt not molest a stranger, for you know the hearts of strangers, for you also were strangers in the land of Egypt." But it is an affliction to be burdened with usury. Therefore the Law unsuitably permitted them ( Deut. 23:19 , 20 ) to lend money to the stranger for usury.
Objection 4: Further, men are much more akin to us than trees. But we should show greater care and love for these things that are nearest to us, according to Ecclus. 13:19 : "Every beast loveth its like: so also every man him that is nearest to himself." Therefore the Lord unsuitably commanded ( Dt. 20:13-19 ) that all the inhabitants of a captured hostile city were to be slain, but that the fruit-trees should not be cut down.
Objection 5: Further, every one should prefer the common good of virtue to the good of the individual. But the common good is sought in a war which men fight against their enemies. Therefore it is unsuitably commanded ( Dt. 20:5-7 ) that certain men should be sent home, for instance a man that had built a new house, or who had planted a vineyard, or who had married a wife.
Objection 6: Further, no man should profit by his own fault. But it is a man's fault if he be timid or faint-hearted: since this is contrary to the virtue of fortitude. Therefore the timid and faint-hearted are unfittingly excused from the toil of battle ( Dt. 20:8 ).
On the contrary, Divine Wisdom declares ( Prov. 8:8 ): "All my words are just, there is nothing wicked nor perverse in them."
I answer that, Man's relations with foreigners are twofold: peaceful, and hostile: and in directing both kinds of relation the Law contained suitable precepts. For the Jews were offered three opportunities of peaceful relations with foreigners. First, when foreigners passed through their land as travelers. Secondly, when they came to dwell in their land as newcomers. And in both these respects the Law made kind provision in its precepts: for it is written ( Ex. 22:21 ): "Thou shalt not molest a stranger [advenam]"; and again ( Ex. 22:9 ): "Thou shalt not molest a stranger [peregrino]." Thirdly, when any foreigners wished to be admitted entirely to their fellowship and mode of worship. With regard to these a certain order was observed. For they were not at once admitted to citizenship: just as it was law with some nations that no one was deemed a citizen except after two or three generations, as the Philosopher says (Polit. iii, 1). The reason for this was that if foreigners were allowed to meddle with the affairs of a nation as soon as they settled down in its midst, many dangers might occur, since the foreigners not yet having the common good firmly at heart might attempt something hurtful to the people. Hence it was that the Law prescribed in respect of certain nations that had close relations with the Jews (viz., the Egyptians among whom they were born and educated, and the Idumeans, the children of Esau, Jacob's brother), that they should be admitted to the fellowship of the people after the third generation; whereas others (with whom their relations had been hostile, such as the Ammonites and Moabites) were never to be admitted to citizenship; while the Amalekites, who were yet more hostile to them, and had no fellowship of kindred with them, were to be held as foes in perpetuity: for it is written ( Ex. 17:16 ): "The war of the Lord shall be against Amalec from generation to generation."
In like manner with regard to hostile relations with foreigners, the Law contained suitable precepts. For, in the first place, it commanded that war should be declared for a just cause: thus it is commanded ( Dt. 20:10 ) that when they advanced to besiege a city, they should at first make an offer of peace. Secondly, it enjoined that when once they had entered on a war they should undauntedly persevere in it, putting their trust in God. And in order that they might be the more heedful of this command, it ordered that on the approach of battle the priest should hearten them by promising them God's aid. Thirdly, it prescribed the removal of whatever might prove an obstacle to the fight, and that certain men, who might be in the way, should be sent home. Fourthly, it enjoined that they should use moderation in pursuing the advantage of victory, by sparing women and children, and by not cutting down fruit-trees of that country.
Reply to Objection 1: The Law excluded the men of no nation from the worship of God and from things pertaining to the welfare of the soul: for it is written ( Ex. 12:48 ): "If any stranger be willing to dwell among you, and to keep the Phase of the Lord; all his males shall first be circumcised, and then shall he celebrate it according to the manner, and he shall be as that which is born in the land." But in temporal matters concerning the public life of the people, admission was not granted to everyone at once, for the reason given above: but to some, i.e. the Egyptians and Idumeans, in the third generation; while others were excluded in perpetuity, in detestation of their past offense, i.e. the peoples of Moab, Ammon, and Amalec. For just as one man is punished for a sin committed by him, in order that others seeing this may be deterred and refrain from sinning; so too may one nation or city be punished for a crime, that others may refrain from similar crimes.
Nevertheless it was possible by dispensation for a man to be admitted to citizenship on account of some act of virtue: thus it is related ( Judith 14:6 ) that Achior, the captain of the children of Ammon, "was joined to the people of Israel, with all the succession of his kindred." The same applies to Ruth the Moabite who was "a virtuous woman" ( Ruth 3:11 ): although it may be said that this prohibition regarded men and not women, who are not competent to be citizens absolutely speaking.
Reply to Objection 2: As the Philosopher says (Polit. iii, 3), a man is said to be a citizen in two ways: first, simply; secondly, in a restricted sense. A man is a citizen simply if he has all the rights of citizenship, for instance, the right of debating or voting in the popular assembly. On the other hand, any man may be called citizen, only in a restricted sense, if he dwells within the state, even common people or children or old men, who are not fit to enjoy power in matters pertaining to the common weal. For this reason bastards, by reason of their base origin, were excluded from the "ecclesia," i.e. from the popular assembly, down to the tenth generation. The same applies to eunuchs, who were not competent to receive the honor due to a father, especially among the Jews, where the divine worship was continued through carnal generation: for even among the heathens, those who had many children were marked with special honor, as the Philosopher remarks (Polit. ii, 6). Nevertheless, in matters pertaining to the grace of God, eunuchs were not discriminated from others, as neither were strangers, as already stated: for it is written ( Isa. 56:3 ): "Let not the son of the stranger that adhereth to the Lord speak, saying: The Lord will divide and separate me from His people. And let not the eunuch say: Behold I am a dry tree."
Reply to Objection 3: It was not the intention of the Law to sanction the acceptance of usury from strangers, but only to tolerate it on account of the proneness of the Jews to avarice; and in order to promote an amicable feeling towards those out of whom they made a profit.
Reply to Objection 4: A distinction was observed with regard to hostile cities. For some of them were far distant, and were not among those which had been promised to them. When they had taken these cities, they killed all the men who had fought against God's people; whereas the women and children were spared. But in the neighboring cities which had been promised to them, all were ordered to be slain, on account of their former crimes, to punish which God sent the Israelites as executor of Divine justice: for it is written ( Dt. 9:5 ) "because they have done wickedly, they are destroyed at thy coming in." The fruit-trees were commanded to be left untouched, for the use of the people themselves, to whom the city with its territory was destined to be subjected.
Reply to Objection 5: The builder of a new house, the planter of a vineyard, the newly married husband, were excluded from fighting, for two reasons. First, because man is wont to give all his affection to those things which he has lately acquired, or is on the point of having, and consequently he is apt to dread the loss of these above other things. Wherefore it was likely enough that on account of this affection they would fear death all the more, and be so much the less brave in battle. Secondly, because, as the Philosopher says (Phys. ii, 5), "it is a misfortune for a man if he is prevented from obtaining something good when it is within his grasp." And so lest the surviving relations should be the more grieved at the death of these men who had not entered into the possession of the good things prepared for them; and also lest the people should be horror-stricken at the sight of their misfortune: these men were taken away from the danger of death by being removed from the battle.
