Genesis 21:9-11

EasyEnglish Bible

⁹ Then Sarah saw that Ishmael was laughing at Isaac. (Ishmael was the son of Abraham and Hagar, the Egyptian servant.) ¹⁰ So Sarah said to Abraham, ‘Send that slave woman and her son away from here. Ishmael must never receive any of our family's things. Everything must belong to my own son, Isaac.’

¹¹ This made Abraham very sad, because Ishmael was his own son.
