Genesis 23

In this passage Abraham's wife dies. He goes to the Hittites to look for a burial place. He asks them for a place to buy and call his own. The people seem to respect him a lot. After some talk and negotiation he buys a field and cave for 400 shekels. I don't know what this means in the large scheme of things. Maybe it just shows how much he loved his wife. I wonder if this place becomes significant later. We'll see.
