Sarah (born Sarai) is the first matriach in the Bible. She travelled with her husband Abraham from Ur to Haran and onward to Canaan where she would eventually become the mother of nations.
Sarah was an unusually attractive woman. The stories in Chapters 12 and 20 of Genesis record how Abraham told Sarah to tell Pharaoh and Abimelech, who found her very desirable, that she was his sister because he was afraid that they would kill him if they knew she was his wife in order to possess her.
When years had passed since God made his promise to Abraham that his descendants would fill the earth and Sarah had not yet borne any children, she suggested Abraham marry her slave-maid Hagar, who bore him a son, Ishmael. A while later, though, God appeared to Abraham and promised him that Sarah would bear a son and become the mother of nations.
"As for Sarai your wife, you are no longer to call her Sarai. Her name will be Sarah. I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations. Kings of peoples will come from her." (Genesis 17:15-16)
Later, when she heard three strangers - who were actually angels in disguise - repeat the promise, she laughed in amusement because she was well past the age of childbearing and Abraham was no spring chicken either. In time, however, Isaac was born. At a feast to celebrate the day Isaac was weaned, Sarah saw that Ishmael, the son whom Hagar had borne to Abraham was mocking, and angrily she told Abraham to get rid of him and his mother.
And she said to Abraham, "Get rid of that slave woman and her son, for that slave woman's son will never share in the inheritance with my son Isaac." (Genesis 21:10)
Sarah died aged 127 (this is the only instance in Scripture where a woman's age is recorded) and was buried by Abraham in the Cave of Machpelah in Hebron. Abraham bought this burial cave from the Hittites. Eventually, Sarah's tomb was used as a family burying-place. Not only was Abraham interred there, but so was Isaac and his wife Rebekah, and then later their grandson Jacob (Israel) and his wife Leah. They all lie there to this day. Today, we know the place as the Tomb of the Patriarchs.
