1 The inscription of a title: of David himself. Preserve me, O Lord, because I have hoped in you.
Origen of Alexandria · AD 253 And again in the fourteenth Psalm he says: "Lord, who shall dwell in thy tabernacle? or who shall rest in thy holy mountain? He that entereth without spot and worketh righteousness" and the rest.
Theodoret of Cyrus · AD 458 Since the psalm before this also prophesied salvation for the inhabitants of Jerusalem and forecast the return of those already made captive, it is right for him to introduce exhortation in this psalm and propose a way of life proper for them to live who are under God's command and enjoying such wonderful assistance.
Thomas Aquinas · AD 1274 Above, the Psalmist treated of the malice and deceit of his adversaries; here he treats of his own justice. And first he shows what kind of justice God accepts. Second, as though giving thanks, he shows the nature of his own justice, at "preserve me." The title: "a Psalm of David." In this Psalm he does two things: for, standing before God as a priest, he consults God.
2 I have said to the Lord: “You are my God, so you have no need of my goodness.”
Ambrose of Milan · AD 397 In everything, therefore, good faith is seemly, justice is pleasing, due measure in equity is delightful. But what shall I say about contracts, and especially about the sale of land, or agreements or covenants? Are there not rules just for the purpose of shutting out all false deceit and to make him whose deceit is found out liable to double punishment?
Benedict of Nursia · AD 548 Brothers, let us hear the Lord's answer to the question, an answer that shows the way to the heavenly tabernacle.… He who drives the tempter and his temptations far from his heart, defeats his malice and dashes his rising thoughts against the Rock Christ.
Thomas Aquinas · AD 1274 "He who." Here the response is set forth, and concerning this he does two things. First he commemorates the merits of those who dwell in the aforesaid places, namely in the tabernacle and on the holy mountain of God. Second, the reward, at "he who does these things shall not be moved forever." He sets forth ten effects of the virtues.
3 As for the saints, who are in his land: he has made all my desires wonderful in them.
Jerome · AD 420 He who has practiced no deceit with his tongue: he who has uttered in speech what he has pondered in his mind. Nor has done evil to his neighbor. Some think that a neighbor is a brother, or a fellow townsman, or a kinsman, or a blood relation.
Augustine of Hippo · AD 430 "Who speaks the truth in his heart." For some have truth on their lips, and not in their heart. As if one should deceitfully point out a road, knowing that there were robbers there, and should say, If you go this way, you will be safe from robbers; and it should turn out that in fact there were no robbers found there: he has spoken the truth, but not in his heart.
Thomas Aquinas · AD 1274 Second, that he should avoid evil, namely deceitfulness. Jer. 9: "Their tongue is a wounding arrow; it has spoken deceit." "He who has not practiced deceit with his tongue." Another reading: "who is not facile with his tongue." Prov.
4 Their infirmities have been multiplied; after this, they acted more quickly. I will not gather for their convocations of blood, nor will I remember their names with my lips.
Diodorus of Tarsus · AD 390 Whoever abhors the wicked, even if they are very rich, while "honoring those who fear the Lord," even if they are very lowly and poor, will live in honor and respect.
Augustine of Hippo · AD 430 "The malicious one has been brought to nought in his sight" [Psalm 15:4]. This is perfection, that the malicious one have no force against a man; and that this be "in his sight;" that is, that he know most surely that the malicious is not, save when the mind turns itself away from the eternal and immutable form of her own Creator to the form of the creature, which was made out…
Thomas Aquinas · AD 1274 Here he forbids deceiving one's neighbor. Now a neighbor is deceived in three ways: namely, in promises, and this through an oath. And so he says, "he who swears," etc. -- that is, he confirms something in order to deceive, because he does not keep it. Zech. 8: "Love not a false oath." Lev.
5 The Lord is the portion of my inheritance and my cup. It is you who will restore my inheritance to me.
Basil of Caesarea · AD 379 We advise the poor … to persevere in their terrible situations rather than to accept the misfortunes that come from the payment of interest. But if you [who are rich] obey the Lord, what need is there of these words? What is the counsel of the Master?
Augustine of Hippo · AD 430 "Who sweareth unto his neighbour, and deceiveth him not." "Who hath not given his money upon usury, and hath not taken rewards against the innocent" (ver. 5).
Thomas Aquinas · AD 1274 Likewise, in contracts; hence: "he who has not lent his money at usury." Lk. 6: "Lend, hoping for nothing in return." "And he has not accepted bribes against the innocent." Prov. 17: "The wicked man accepts a bribe from the bosom," that is, of the Church, "to pervert the paths of justice." Deut.
6 The lots have fallen upon me with clarity. And, indeed, my inheritance has been very clear to me.
7 I will bless the Lord, who has bestowed understanding upon me. Moreover, my temperament has also corrected me, even through the night.
8 I have made provision for the Lord always in my sight. For he is at my right hand, so that I may not be disturbed.
9 Because of this, my heart has been joyful, and my tongue has exulted. Moreover, even my body will rest in hope.
10 For you will not abandon my soul to Hell, nor will you allow your holy one to see corruption.
11 You have made known to me the ways of life; you will fill me with joy by your countenance. At your right hand are delights, even to the end.
