Genesis 23:7-9

7Then Abraham rose and bowed down to the Hethites, the people of the land.

8He said to them, “If you are willing for me to bury my dead, listen to me and ask Ephron son of Zohar on my behalf

9to give me the cave of Machpelah that belongs to him; it is at the end of his field. Let him give it to me in your presence, for the full price, as burial property.”
