1 And the Lord visited Sara, as he had promised: and fulfilled what he had spoken. 2 And she conceived and bore a son in her old age, at the time that God had foretold her. 3 And Abraham called the name of his son, whom Sara bore him, Isaac. 4 And he circumcised him the eighth day, as God had commanded him, 5 When he was a hundred years old: for at this age of his father was Isaac born.
3 "Isaac"... This word signifies laughter.
6 And Sara said: God hath made a laughter for me: whosoever shall hear of it will laugh with me. 7 And again she said: Who would believe that Abraham should hear that Sara gave suck to a son, whom she bore to him in his old age. 8 And the child grew and was weaned: and Abraham made a great feast on the day of his weaning. 9 And when Sara had seen the son of Agar the Egyptian playing with Isaac her son, she said to Abraham: 10 Cast out this bondwoman, and her son: for the son of the bondwoman shall not be heir with my son Isaac.
