Genesis 16 talks about Hagar who was Abram's maidservant. Sarai was Abram's wife and she was unable to have children so she told Abram to sleep with Hagar and to have children and build a family through her.
6 "Your servant is in your hands," Abram said. "Do with her whatever you think best." Then Sarai mistreated Hagar; so she fled from her.
7 The angel of the LORD found Hagar near a spring in the desert; it was the spring that is beside the road to Shur. 8 And he said, "Hagar, servant of Sarai, where have you come from, and where are you going?"
"I'm running away from my mistress Sarai," she answered.
9 Then the angel of the LORD told her, "Go back to your mistress and submit to her." 10 The angel added, "I will so increase your descendants that they will be too numerous to count."
11 The angel of the LORD also said to her:
"You are now with child
and you will have a son.
You shall name him Ishmael, [a]
for the LORD has heard of your misery.
12 He will be a wild donkey of a man;
his hand will be against everyone
and everyone's hand against him,
and he will live in hostility
toward [b] all his brothers."
13 She gave this name to the LORD who spoke to her: "You are the God who sees me," for she said, "I have now seen [c] the One who sees me." 14 That is why the well was called Beer Lahai Roi [d] ; it is still there, between Kadesh and Bered.
15 So Hagar bore Abram a son, and Abram gave the name Ishmael to the son she had borne. 16 Abram was eighty-six years old when Hagar bore him Ishmael.
So Ishmael was Abram's first child. Ishmael would be despised by all and he would be against everyone living in hostility against his brothers. Ishmael means "God hears" because God heard the cries of Hagar. Beer Lahai Roi means well of the Living One who sees me. Praise the Lord for watching over us.
