Genesis 23

After sticking to God’s previously mandated lifespan of 120 years (okay, 127 years, but who’s counting), Sarah croaked. Abraham, being a habitual mooch, asked the sons of Heth for a place to bury his wife. The children of Heth, knowing what happened to people who messed with Abraham, offered him any tomb he could find.

So, Abraham picked a cave to bury Sarah in, and offered Ephron (apparently the real estate agent) four hundred shekels of silver for the property. Ephron, not wanting to risk eternal damnation, told Abraham the land was crap anyway, so no payment was needed. Suddenly deciding he should start paying for the stuff he took, Abraham paid Ephron anyway, and planted his dead wife in a cave that he now owned free and clear.
