The angel of the LORD came upon Hagar by a spring in the wilderness, the spring on the road to Shur, and he said: [...] You are with child and will bear a son. You are to name him Ishmael, because the Lord has heard of your ill-treatment. He will be like the wild ass; his hand will be against everyone and everyone's hand against him; and he will live at odds with all his kin.
Genesis 16:7-12
