I Kings 17:4-7

And it will be that you shall drink from the brook, and I have commanded the ravens to feed you there.” So he went and did according to the word of the LORD, for he went and stayed by the Brook Cherith, which flows into the Jordan. The ravens brought him bread and meat in the morning, and bread and meat in the evening; and he drank from the brook. And it happened after a while that the brook dried up, because there had been no rain in the land.
