19 What shall I say of Abraham who had three wives, as Jovinianus says, and received circumcision as a sign of his faith? If we follow him in the number of his wives, let us also follow him in circumcision. We must not partly follow, partly reject him. Isaac, moreover, the husband of one wife, Rebecca, prefigures the Church of Christ, and reproves the wantonness of second marriage. And if Jacob had two pairs of wives and concubines, and our opponent will not admit that blear-eyed Leah, ugly and prolific, was a type of the synagogue, but that Rachel, beautiful and long barren, indicated the mystery of the Church, let me remind him that when Jacob did this thing he was among the Assyrians, and in Mesopotamia in bondage to a hard master.
But when he wished to enter the holy land, he raised on Mount Galeed the heap of witness, in token that the lord of Mesopotamia had failed to find anything among his baggage, and there swore that he would never return to the place of his bondage; and when, after wrestling with the angel at the brook Jabbok, he began to limp, because the great muscle of his thigh was withered, he at once gained the name of Israel. Then the wife whom he once loved, and for whom he had served, was slain by the son of sorrow near Bethlehem which was destined to be the birthplace of our Lord, the herald of virginity: and the intimacies of Mesopotamia died in the land of the Gospel.
