Genesis 24:1-6
The Wife for Isaac
24:1 Now Abraham was old, well advanced in years, and the Lord had blessed him in everything.
24:2 Abraham said to his servant, the senior one in his household who was in charge of everything he had, “Put your hand under my thigh
24:3 so that I may make you solemnly promise by the Lord, the God of heaven and the God of the earth: You must not acquire a wife for my son from the daughters of the Canaanites, among whom I am living.
24:4 You must go instead to my country and to my relatives to find a wife for my son Isaac.”
24:5 The servant asked him, “What if the woman is not willing to come back with me to this land? Must I then take your son back to the land from which you came?”
24:6 “Be careful never to take my son back there!” Abraham told him.
