The field which Abraham purchased of the children of Heth. There was Abraham buried, and Sarah his wife.

the field and the cave that is therein, which was purchased from the children of Heth.

Terror and dread falleth upon them; By the greatness of thine arm they are as still as a stone; Till thy people pass over, O Jehovah, Till the people pass over that thou hast purchased.

Moreover Ruth the Moabitess, the wife of Mahlon, have I purchased to be my wife, to raise up the name of the dead upon his inheritance, that the name of the dead be not cut off from among his brethren, and from the gate of his place: ye are witnesses this day.
