The angel of the Lord found her by a spring of water in the wilderness, the spring on the way to Shur. - Genesis 16:7
Hagar fled to the wilderness from her harsh mistress Sarai when pregnant with Ishmael. The angel of the Lord saw her there by a spring of water on the way to Shur. The well was called Beer-lahai-roi, and it lies between Kadesh and Bered. (Genesis 16)
