Isaac at Forty and Rebekah at Three When They Married

"And Isaac was forty years old when he took Rebekah" (Genesis 25:20). Isaac our father was thirty-seven years old when he was bound upon the altar. In that same period Sarah died, and in that same period Rebekah was born. It is found that Rebekah was married to Isaac when she was three years old. [Reckoning: Isaac was born when Sarah was ninety; she died at one hundred and twenty-seven, so Isaac was thirty-seven at the binding, when she died and Rebekah was born. Isaac married at forty, three years later, so Rebekah was three.]
