Genesis 23:15

12 And Abraham went down on his face before the people of the land.

13 And Abraham said to Ephron, in the hearing of the people of the land, If only you will give ear to me, I will give you the price of the field; take it, and let me put my dead to rest there.

14 So Ephron said to Abraham,

15 My lord, give ear to me: the value of the land is four hundred shekels; what is that between me and you? so put your dead to rest there.

16 And Abraham took note of the price fixed by Ephron in the hearing of the children of Heth, and gave him four hundred shekels in current money.

17 So Ephron's field at Machpelah near Mamre, with the hollow in the rock and all the trees in the field and round it,

18 Became the property of Abraham before the eyes of the children of Heth and of all who came into the town.
