So Ephron's land in Machpelah, near Mamre—the field with its cave and all the trees anywhere within the confines of that field—passed to Abraham as his possession, in the presence of the Hittites, of all who entered the gate of his town. And then Abraham buried his wife Sarah in the cave of the field of Machpelah, facing Mamre—now Hebron—in the land of Canaan. Thus the field with its cave passed from the Hittites to Abraham, as a burial site.
Abraham was now old, advanced in years, and the Lord had blessed Abraham in all things. And Abraham said to the senior servant of his household, who had charge of all that he owned, "Put your hand under my thigh and I will make you swear by the Lord, the God of heaven and the God of the earth, that you will not take a wife for my son from the daughters of the Canaanites among whom I dwell, but will go to the land of my birth and get a wife for my son Isaac." And the servant said to him, "What if the woman does not consent to follow me to this land, shall I then take your son back to the land from which you came?" Abraham answered him, "On no account must you take my son back there! The Lord, the God of heaven, who took me from my father's house and from my native land, who promised me on oath, saying, 'I will assign this land to your offspring'—He will send His angel before you, and you will get a wife for my son from there. And if the woman does not consent to follow you, you shall then be clear of this oath to me; but do not take my son back there." So the servant put his hand under the thigh of his master Abraham and swore to him as bidden.
