Then Abraham arose from mourning before his dead, and spoke to the sons of Heth, saying, “I am a stranger and a foreign resident among you; give me a burial site among you so that I may bury my dead out of my sight.”
Genesis 23:3-4 (NASB)
There are layers to scripture. Genesis 23 contains a long text about Abraham seeking a burial site for Sarah. It's not just a story about negotiating over a plot of land.
Heth is the son of Canaan, son of Ham.
Heth means "terror."
This is a story about dealing with the terror and agony of death.
