What name did Hagar give the LORD who spoke to her in the wilderness?

Answer: The God who sees me

Hagar called the LORD "You are the God who sees me," and the well there was named Beer-lahai-roi.

“So Hagar gave this name to the LORD who had spoken to her: “You are the God who sees me,” for she said, “Here I have seen the One who sees me!” Therefore the well was called Beer-lahai-roi. It is located between Kadesh and Bered.”— Genesis 16:13-14 (BSB)
