Isaac grew, and Sarah noticed that Ishmael, Isaac's older half-brother, was a potentially negative influence on her young child. She demanded of Abraham to expel Ishmael, along with his mother Hagar, from the household. Despite Abraham's initial misgivings, G‑d tells him: "Whatever Sarah tells you, listen to her voice!" Hagar and Ishmael wandered in the desert and eventually ran out of water. Ishmael was about to perish from thirst when an angel "opened Hagar's eyes" and showed her a well of water. Ishmael grew up in the desert and became a skilled archer.
