Genesis 24
2 Ref Abraham said to his servant, the elder of his house, who ruled over all that he had, "Please put your hand under my thigh.
3 Ref I will make you swear by Yahweh, the God of heaven and the God of the earth, that you shall not take a wife for my son of the daughters of the Canaanites, among whom I live.
4 Ref But you shall go to my country, and to my relatives, and take a wife for my son Isaac."
5 Ref The servant said to him, "What if the woman isn't willing to follow me to this land? Must I bring your son again to the land you came from?"
