Gênesis 12
Augustine of Hippo · Comentário Patrístico (catena)
Gênesis 12:1
The right thing to do, brothers and sisters, is to believe God before he pays up anything, because just as he cannot possibly lie, so he cannot deceive. For he is God. That's how our ancestors believed him. That's how Abraham believed him. There's a faith for you that really deserves to be admired and made widely known. He had received nothing from him, and he believed his promise. We do not yet believe him, though we have already received so much. Was Abraham ever in a position to say to him, "I will believe you, because you promised me that and paid up"? No, he believed from the very first command given, without having received anything else at all. "Go out from your country," he was told, "and from your kindred, and go into a country which I will give you." And he believed straightaway, and [God] didn't give him that country but kept it for his seed. — SERMON 113A.10
Gênesis 12:13
Having built an altar there and called upon God, Abraham proceeded thence and dwelt in the desert and was compelled by pressure of famine to go on into Egypt. There he called his wife his sister, and he told no lie. For she was this also, because she was near of blood; just as Lot, on account of the same nearness, being his brother's son, is called his brother. Now he did not deny that she was his wife but held his peace about it, committing to God the defense of his wife's chastity and providing as a man against human wiles. If he had not provided against the danger as much as he could, he would have been tempting God rather than trusting in him. We have said enough about this matter against the calumnies of Faustus the Manichaean. At last what Abraham had expected the Lord to do took place. For Pharaoh, king of Egypt, who had taken her to him as his wife, restored her to her husband when faced with severe plague. And far be it from us to believe that she was defiled by lying with another. It is much more credible that, by these great afflictions, Pharaoh was not permitted to do this. — City of God 16.19
