Genesis 23:7-9

7Abraham stood up. He turned his face towards the ground to respect the Hittites who lived in that place.

8He said to them, ‘Since you have agreed to help me, please do this. Speak to Zohar's son, Ephron, for me.

9Ask him to sell the cave of Machpelah to me. It belongs to Ephron. It is at the edge of his field. You will see that I pay the proper price to him. Then it will belong to me. I can bury my family there when they die.’
