Genesis 24:1-8

Abraham was now an old man. GOD had blessed Abraham in every way. Abraham spoke to the senior servant in his household, the one in charge of everything he had, “Put your hand under my thigh and swear by GOD—God of Heaven, God of Earth—that you will not get a wife for my son from among the young women of the Canaanites here, but will go to the land of my birth and get a wife for my son Isaac.” The servant answered, “But what if the woman refuses to leave home and come with me? Do I then take your son back to your home country?” Abraham said, “Oh no. Never. By no means are you to take my son back there. GOD, the God of Heaven, took me from the home of my father and from the country of my birth and spoke to me in solemn promise, ‘I’m giving this land to your descendants.’ This God will send his angel ahead of you to get a wife for my son. And if the woman won’t come, you are free from this oath you’ve sworn to me. But under no circumstances are you to take my son back there.”
