TSK · Genesis 25:10

if 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.”

So Abraham secured Ephron’s field in Machpelah, next to Mamre, including the field, the cave that was in it, and all the trees that were in the field and all around its border,

There they buried Abraham and his wife Sarah; there they buried Isaac and his wife Rebekah; and there I buried Leah.
