Then a revelation from the Lord came to him:
"Leave here, turn eastward, and hide yourself at the Wadi Cherith where it enters the Jordan.
You are to drink from the wadi. I have commanded the ravens to provide for you there."

The ravens kept bringing him bread and meat in the morning and in the evening, and he drank from the wadi.
