Genesis 23:7-9

7Then Abraham rose and bowed down before the people of the land, the Hittites. 8“If you are willing for me to bury my dead,” he said to them, “listen to me, and approach Ephron son of Zohar on my behalf 9to sell me the cave of Machpelah that belongs to him; it is at the end of his field. Let him sell it to me in your presence for full price, so that I may have a burial site.”
