² And Abraham said to his servant, the oldest of his house, who had charge of all that he had, “Put your hand under my thigh, ³ and I will make you swear by the Lord, the God of heaven and of the earth, that you will not take a wife for my son from the daughters of the Canaanites, among whom I dwell, ⁴ but will go to my country and to my kindred, and take a wife for my son Isaac.”
