Sarah or Sara was the wife and half-sister of Abraham in the Old Testament book of Genesis (Chapters 12-23). They got married in Haran. She was barren for a long period. She had a child with Abraham named Isaac when she was 90. She lived until she was 127, and was buried by Abraham in Hebron in what is now the West Bank. Her name was Sarai but God changed it to Sarah.
