Sarah lived to be 127 years old.
References for Genesis 23:1
She died at Kiriath Arba. Kiriath Arba is also called Hebron. It's in the land of Canaan. Sarah's death filled Abraham with sorrow. He went to the place where her body was lying. There he sobbed over her.
Then Abraham got up from beside his dead wife. He spoke to the Hittites. He said,
"I'm an outsider. I'm a stranger among you. Sell me some property here as a place for a family tomb. Then I can bury my wife's body.
The Hittites replied to Abraham,
"Sir, listen to us. You are a mighty prince among us. Bury your dead wife in the best of our tombs. None of us will refuse to sell you his tomb for burying her."
