When Abram was circumcised, G-d changed his name to Abraham. And Ishmael was also circumcised and was thirteen years old at the time. One year later, Sarai whose name was now Sarah gave birth to a son while she was 90 years old and Abraham was 100. Abraham circumcised the boy eight days later and named him Isaac. When Sarah saw how Ishmael played with his half-brother Isaac, she told Abraham “cast out this slave woman and her son from before me” but Abraham didn’t want to do that so G-d told Abraham to listen to Sarah. So Abraham sent Ishmael and Hagar away with water. Then Ishmael got sick so Hagar gave him all the water and then looked for more so an Angel showed her a well. Hagar gave Ishmael water and he got better. Ishmael went to Egypt, married an Egyptian woman and became the father of twelve sons and one daughter.
