Genesis 23

In Genesis 23, Abraham loses Sarah. She was 127 years old when she died and they had lived a full life of tents and altars before God. They were in Canaan living as foreigners. This was the very land God promised Abraham his descendants would be given. He purchases a plot of land at the highest opening bid price and buries Sarah. He essentially makes an investment into the very land God had promised his descendants would claim some day.  He paid the highest price for it ensuring he leaves no debts behind as he now realizes he is just passing through here. This parallels Jesus when He passed through on Earth and took all of our debts to sin with Him on the cross. He paid the highest possible price and invested in us so we could live eternally with Him and be free from the chains of sin and death.
