Genesis 23:7-9

7Abraham got up and bowed down to the local people, the sons of Heth.

8Then he said to them, “If you agree that I may bury my dead, then hear me out. Ask Ephron the son of Zohar

9if he will sell me the cave of Machpelah that belongs to him; it is at the end of his field. Let him sell it to me publicly for the full price, so that I may own it as a burial site.”
