25:30
(Verse 30) And Esau said to Jacob: Give me a taste of that red stew, for I am famished. That is why he was called Edom. Red or tawny is called Edom in the Hebrew language. Therefore, from the fact that he sold his birthright for red food, he obtained the name Edom, which means tawny.
26:12
(Chapter 26, verse 12) And Isaac sowed in that land, and in that year he reaped a hundredfold. Although Isaac sowed in a foreign land, I do not think that such fertility of barley would have been to him. Therefore, I think the Hebrew version is better, and even Aquila translated it: And he reaped in that year a hundredfold estimated, that is, ἑκατὸν εἰκασμένον. Although the same letters are used for both estimation and barley, the estimations are read as Saarim (), and the barleys as Sorim. But Scripture, however, seems to me to have shown in it the multiplication of all virtues, in that it has increased a hundredfold the type of fruits.
26:13
(Verse 13.) And the Lord blessed him, and he became a great man, and he walked, going forth, and he was greatly magnified, until he became exceedingly great. But the abundance of barley, I do not know if it can make anyone glorious.
26:17
(Verse 17.) And Isaac departed from there and came to the valley of Gerar, and he dwelt there. The valley has a stream in Hebrew. For Isaac could not dwell in the valley after he became great. However, he dwelt by the stream, of which it is written: He shall drink from the brook by the way (Psalm 110:7). Also, during the time of famine, Elijah drank from that stream. But because Elijah was not perfect like Christ, therefore that stream dried up for him (1 Kings 17:7). Our Lord, indeed, was also handed over in the river: consecrating our regeneration and the sacrament of Baptism.
26:19
(Verse 19) And the servants of Isaac dug in the valley of Gerar and found there a well of living water. And for this valley, a stream was written; for never is a well of living water found in the valley.
26:21
(Verse 21.) And they dug another well, and they quarreled over it. And he called its name Enmity. Concerning enmity, because Aquila and Symmachus translated it as τὴν ἀντικειμένην, and ἐναντίωσιν, which means opposing and contrary, in Hebrew it is Satana (). From which we understand Satana to be interpreted as the opposite.
26:22
(Verse 22.) And they dug another well, and they did not quarrel over it: so he called its name Broad Places; or, in Hebrew, Rehoboth, to prove what we have said above, that he himself built the city of Nineveh and its broad places (Genesis 10).
26:26
(Verse 26.) And Abimelech went to him from Gerar, and Ahuzzath his counselor, and Phicol the commander of his army. Regarding Ahuzzath his counselor, in Hebrew it means his group of friends: it signifies not so much a single person as a crowd of friends who came with the king, among whom was also Phicol the commander of his army.
26:32-33
(Verse 32 and 33.) And the servants of Isaac came and told him about the well that they had dug, and they said to him, 'We have found water.' So he called it Shebah. I don't know how it is translated in the Septuagint: 'And the servants of Isaac came and told him about the well that they had dug, and they said to him, 'We have not found water.' So he called it Oath.' What is the etymology behind calling it Oath just because they did not find water? On the contrary, in Hebrew, which Aquila and Symmachus agree with in interpretation, this signifies that they found water, and therefore the well itself was called Saturation, and the city was called Beersheba, which means well of saturation (Gen. XXI): for although above we asserted that Beersheba was called so from the word of the oath, or from the number seven of the sheep, which is called Sabee, now because water was found, Isaac turned slightly the letter to the name of the city, which was thus called alluding, and instead of the harsh sound of the Hebrews Sin, from which Sabee begins, he placed the Greek sigma, which is the Hebrew Samech: otherwise, according to the law of allegory, after so many wells at the end of virtues, it does not at all agree that Isaac did not find water.
27:11
(Chapter XXVII, Verse 11) Behold, Esau my brother is a hairy man, and I am a smooth man. Where it is written that he was hairy, in Hebrew it is written Seir (). Therefore, afterwards the mountains of Seir and the region in which he lived were called Seir: we have spoken of this before and above.
27:15
(Verse 15) And Rebecca took the garments of her elder son Esau, which were greatly desired by him at home. And in this place, the Hebrews tradition holds that the firstborns, who had fulfilled the duties of the priests, had a priestly garment, which they wore to offer sacrifices to God before Aaron was chosen for the priesthood.
27:36
(Verse 36.) And Esau said, rightly is his name called Jacob: for he hath supplanted me these two times. Jacob is interpreted supplanter. And therefore, because he had deceived his brother by art, he alluded to the name. Therefore, he was called Jacob before, because he had taken hold of his brother's heel in his birth.
