Genesis 24:1-8

Now, YAHWEH had wonderfully blessed Abraham in every way, and he became a very old man, well advanced in years. One day, Abraham called for his trusted head servant, who was in charge of all that he had, and said “Please, put your hand here under my thigh, and I will make you swear by YAHWEH, the God of heaven and earth, that you will not acquire a wife for my son among the daughters of the Canaanites among whom I am living. Promise me you will go instead to my relatives in my native land and find a wife among them for my son Isaac.” The servant asked him, “Suppose the woman is not willing to come back with me to this land. Should I then take your son back to your native land?” “Absolutely not,” Abraham answered, “make sure that you do not take my son back there. For YAHWEH, the God of heaven, took me from my father’s house and from the land of my birth. He spoke to me and solemnly promised that he would give this land to my descendants. I know he will send his angel before you so that you can find a wife for my son from there. And if for any reason the woman is unwilling to come back with you, then you are released from this oath that you swear to me. But no matter what, do not take my son back there!”
