El-Roi is one of my favourite names of God, if not my favourite.
It is a name given to God by Hagar, the mother of Ishmael. The account is recorded in Genesis 16. Sarah and Abraham and growing old and restless. God seems not to be aware that time is running out on His promise to make them father and mother of nations. So Sarah comes up with he idea that maybe God meant to give them children through another, and her another is Hagar who is her handmaid. Abraham, reminds me of Adam in the garden, goes along with Sarah’s suggestion and sleeps with Hagar.
