1 Kings 17-17.7
Now Elijah the Tishbite, of Tishbe in Gilead, said to Ahab, "As the Lord the God of Israel lives, before whom I stand, there shall be neither dew nor rain these years, except by my word."
And the word of the Lord came to him, "Depart from here and turn eastward, and hide yourself by the brook Cherith, that is east of the Jordan. 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; he went and dwelt by the brook Cherith that is east of the Jordan. And the ravens brought him bread and meat in the morning, and bread and meat in the evening; and he drank from the brook.
And after a while the brook dried up, because there was no rain in the land.
