The Birth of Isaac

Genesis 21

¹ And the LORD _a visited Sarah as He had said, and the LORD did for Sarah _b as He had spoken. ² For Sarah _c conceived and bore Abraham a son in his old age, _d at the set time of which God had spoken to him. ³ And Abraham called the name of his son who was born to him - whom Sarah bore to him - _e Isaac. ₁ ⁴ Then Abraham _f circumcised his son Isaac when he was eight days old, _g as God had commanded him. ⁵ Now _h Abraham was one hundred years old when his son Isaac was born to him. ⁶ And Sarah said, _i "God has ₂ made me laugh, and all who hear _j will laugh with me." ⁷ She also said, "Who would have said to Abraham that Sarah would nurse children? _k For I have borne him a son in his old age."
