Genesis 16:6-7

16:6 Abram said to Sarai, “Since your servant is under your authority, do to her whatever you think best.” Then Sarai treated Hagar harshly, so she ran away from Sarai.

16:7 The Lord’s angel found Hagar near a spring of water in the desert – the spring that is along the road to Shur.

Genesis 16:13-14

16:13 So Hagar named the Lord who spoke to her, “You are the God who sees me,” for she said, “Here I have seen one who sees me!” 16:14 That is why the well was called Beer Lahai Roi. (It is located between Kadesh and Bered.)
