way back in Genesis 12, God promised Abraham that he would make him into a great nation; but Abraham and his wife were old and they had no children. in chapter 16, they get impatient and force the promise to come faster. Abraham’s wife Sarah tells Abraham to sleep with her Egyptian servant Hagar and he does. (which also raises some questions; because that’s a wrong thing to do…right? God never brings it up.)
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,
for the LORD has heard of your misery.”
“Hagar gave this name to the LORD who spoke to her: "You are the God who sees me," for she said, "I have now seen the One who sees me."
