Genesis 21:1-7

Young's Literal Translation

21 And Jehovah hath looked after Sarah as He hath said, and Jehovah doth to Sarah as He hath spoken;

² and Sarah conceiveth, and beareth a son to Abraham, to his old age, at the appointed time that God hath spoken of with him;

³ and Abraham calleth the name of his son who is born to him, whom Sarah hath born to him -- Isaac;

⁴ and Abraham circumciseth Isaac his son, [being] a son of eight days, as God hath commanded him.

⁵ And Abraham [is] a son of a hundred years in Isaac his son being born to him,

⁶ and Sarah saith, `God hath made laughter for me; every one who is hearing laugheth for me.'

⁷ She saith also, `Who hath said to Abraham, Sarah hath suckled sons, that I have born a son for his old age?'
