Genesis 21:5 CPDV

³  And Abraham called the name of his son, whom Sarah bore for him, Isaac.

⁴  And he circumcised him on the eighth day, just as God had instructed him,

⁵  when he was one hundred years old. Indeed, at this stage of his father's life, Isaac was born.

⁶  And Sarah said: 'God has brought laughter to me. Whoever will hear of it will laugh with me.'

⁷  And again, she said: 'Hearing this, who would believe Abraham, that Sarah breast-fed a son, to whom she gave birth, despite being elderly?'
