Genesis 24:3-8

3that I may make you swear by the Lord, the God of heaven and God of the earth, that ayou will not take a wife for my son from the daughters of the Canaanites, among whom I dwell, 4 bbut will go to my country and to my kindred, and take a wife for my son Isaac.” 5The servant said to him, “Perhaps the woman may not be willing to follow me to this land. Must I then take your son back to the land from which you came?” 6Abraham said to him, “See to it that you do not take my son back there. 7The Lord, the God of heaven, cwho took me from my father’s house and from the land of my kindred, and who spoke to me and swore to me, d‘To your offspring I will give this land,’ ehe will send his angel before you, and you shall take a wife for my son from there. 8But if the woman is not willing to follow you, then fyou will be free from this oath of mine; only you must not take my son back there.”
