Joshua 24:3

3.And I took your father Abraham, etc This expression gives additional confirmation to what I lately showed, that Abraham did not emerge from profound ignorance and the abyss of error by his own virtue, but was drawn out by the hand of God. For it is not said that he sought God of his own accord, but that he was taken by God and transported elsewhere. Joshua then enlarges on the divine kindness in miraculously preserving Abraham safe during his long pilgrimage. What follows, however, begets some doubt, namely, that God multiplied the seed of Abraham, and yet gave him only Isaac, because no mention is made of any but him. But this comparison illustrates the singular grace of God towards them in that, while the offspring of Abraham was otherwise numerous, their ancestor alone held the place of lawful heir. In the same sense it is immediately added, that while Esau and Jacob were brothers and twins, one of the two was retained and the other passed over. We see, therefore, why as well in the case of Ishmael and his brother as in that of Esau, he loudly extols the divine mercy and goodness towards Jacob, just as if he were saying, that his race did not excel others in any respect except in that of being specially selected by God.
