Gen 16:1 Now Sarai, Abram’s wife, had borne him no children. She had a female Egyptian servant whose name was Hagar.
Gen 16:3 So, after Abram had lived ten years in the land of Canaan, Sarai, Abram’s wife, took Hagar the Egyptian, her servant, and gave her to Abram her husband as a wife.
Gen 16:4 And he went in to Hagar, and she conceived. And when she saw that she had conceived, she looked with contempt on her mistress.
Gen 16:8 And he said, “Hagar, servant of Sarai, where have you come from and where are you going?” She said, “I am fleeing from my mistress Sarai.”

Gen 16:15 And Hagar bore Abram a son, and Abram called the name of his son, whom Hagar bore, Ishmael.
Gen 16:16 Abram was eighty-six years old when Hagar bore Ishmael to Abram.

Gen 21:9 But Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, laughing.
Gen 21:14 So Abraham rose early in the morning and took bread and a skin of water and gave it to Hagar, putting it on her shoulder, along with the child, and sent her away. And she departed and wandered in the wilderness of Beersheba.

Gen 21:17 And God heard the voice of the boy, and the angel of God called to Hagar from heaven and said to her, “What troubles you, Hagar? Fear not, for God has heard the voice of the boy where he is.

Gen 25:12 These are the generations of Ishmael, Abraham’s son, whom Hagar the Egyptian, Sarah’s servant, bore to Abraham.
