Ambrose of Milan : So Abraham left, taking with him his wife Sarah, which means "sovereign," not "servant." Therefore it was said to Abraham, "Listen to your wife Sarah." In fact, she who is liberated from the slavery of sin obtains sovereignty, not servitude. Therefore a sound mind possesses sovereign virtue, which has dominion over the bodily senses, which is not subject, which has brought back everything from Egypt, which has not left there any of the norms that regulate her life. Such a mind is not clothed with intemperance or insolence or shameful immodesty. Nor is it lacking the veil of prudent wisdom, and it is clothed with modesty. — ON ABRAHAM 2.5.19 Bede : Abram went up therefore from Egypt, he and his wife, and all that he had, and Lot with him, to the southern region. He does not mean the southern region of Egypt, but of the promised land: for indeed he did not travel southward from Egypt, which whoever does, goes farther from the promised land: but leaving all of Egypt, part of which he had visited, he first ascended to the southern region of the promised land, which was nearest. It should also be noted according to the letter that Abraham is remembered as having previously descended into Egypt, and now ascending from Egypt, because certainly the land of Egypt is considered inferior not only to the land of Canaan but also to other regions of the world, just as conversely the region of the Scythians is said to be elevated higher than other parts of the earth: which can be easily inferred from the courses of the rivers flowing into it from elsewhere and flowing out from it. It fits however most aptly with the typical senses that the land of Canaan should be higher than Egypt, because this indeed represents the promise of the heavenly homeland, while that signifies the oppressions and labors of present life. For this the Lord both promised and gave as an inheritance to his people Israel: but in that land both Abraham encountered peril, though protected immediately by the Lord, and his progeny were for a long time oppressed by a severe servitude, although they themselves were at last miraculously redeemed and led out from there. Therefore the land of promise is higher than the boundaries of Egypt, although situated nearby, because even if the just and the reprobate appear to live a common life outwardly in this age, yet with the great sublimity of a devoted mind, the citizens of heaven surpass all the lovers of this world. Therefore what is said about Abraham that he went up from Egypt, and came with all his own to the southern region, signifies typically that he himself while living in the flesh, and all the elect, that is the children of the same promise, thus for a time turn their thoughts to caring for bodily necessities in the lowest things, so that soon, having fulfilled the same care of the body, they may recall the whole intention of the mind to contemplate the things that are above, and seek to be renewed by the fervor of love and the light of heavenly grace from the Sun of righteousness: for this is mystically to go up from Egypt to the southern region, after fulfilling the necessities of the flesh, to ask diligently from the Lord for progress in the light of the heavenly and of charity. For with such a desire and purpose of mind it is no doubt that we make our journey to the heavenly homeland: whence it is aptly added. — Commentary on Genesis (Hexaemeron)
