Genesis 23:1-9

And the life of Sarah was a hundred and seven and twenty years: these were the years of the life of Sarah. And Sarah died in Kiriath-arba (the same is Hebron), in the land of Canaan: and Abraham came to mourn for Sarah, and to weep for her. And Abraham rose up from before his dead, and spake unto the children of Heth, saying, I am a stranger and a sojourner with you: give me a possession of a burying-place with you, that I may bury my dead out of my sight. And the children of Heth answered Abraham, saying unto him, Hear us, my lord; thou art a prince of God among us: in the choice of our sepulchres bury thy dead; none of us shall withhold from thee his sepulchre, but that thou mayest bury thy dead. And Abraham rose up, and bowed himself to the people of the land, even to the children of Heth. And he communed with them, saying, If it be your mind that I should bury my dead out of my sight, hear me, and entreat for me to Ephron the son of Zohar, that he may give me the cave of Machpelah, which he hath, which is in the end of his field; for the full price let him give it to me in the midst of you for a possession of a burying-place.
