ASV notes on Genesis 16:14-16

God by a well, saved Hagar’s life and she named the well, Beer-lahai-roi, the living one who sees me, it is between Kadesh and Bered and testifies about God being fair and good.

Hagar gave birth to a son and named him Ishmael as the angel told her. Ishmael means God hears. Every time people used the name of the well, they talked about God, and when they said Ishmael they talked about God, God sees and God hears. God is the same today as then.
