Genesis 24:1-9

1Now 1Abraham was old, advanced in age; and the Lord had 2blessed Abraham in every way. 2Abraham said to his servant, the oldest of his household who was in 3charge of all that he owned, “4Please place your hand under my thigh, 3and I will make you swear by the Lord, 5the God of heaven and the God of earth, that you 6shall not take a wife for my son from the daughters of 7the Canaanites, among whom I live; 4but you will go to 8my country and to my relatives, and take a wife for my son Isaac.” 5The servant said to him, “Suppose the woman is not willing to follow me to this land; should I take your son back to the land from where you came?” 6Then Abraham said to him, “9Beware that you do not take my son back there! 710The Lord, the God of heaven, who took me from my father’s house and from the land of my birth, and who spoke to me and who swore to me, saying, ‘11To your 12descendants I will give this land’--He will send 13His angel ahead of you, and you will take a wife for my son from there. 8But if the woman is not willing to follow you, then you will 14be free of this oath of mine; 15only do not take my son back there.” 9So the servant 16placed his hand under the thigh of his master Abraham, and swore to him concerning this matter.
