Ephron was a Hittite from whom Abraham purchased a field containing the cave of Machpelah.
It became the burial place for Abraham, Isaac, and Jacob, and their wives, Sarah, Rebekah, and Leah.
Abraham was not a land owner at the time, and had no family tomb to bury his wife, Sarah, when she died at Hebron. When Abraham asked to buy the cave that belonged to Ephron, Ephron offered the cave as a gift. But Abraham refused the gift and instead paid Ephron 400 shekels for the property. (Gen. 23:1-20).
