Genesis 21:6 YLT

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?'

⁸  And the lad groweth, and is weaned, and Abraham maketh a great banquet in the day of Isaac's being weaned;
