1 Kings 17:1-7 (ESV)
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.” 2 And the word of the Lord came to him: 3 “Depart from here and turn eastward and hide yourself by the brook Cherith, which is east of the Jordan. 4 You shall drink from the brook, and I have commanded the ravens to feed you there.” 5 So he went and did according to the word of the Lord. He went and lived by the brook Cherith that is east of the Jordan. 6 And the ravens brought him bread and meat in the morning, and bread and meat in the evening, and he drank from the brook. 7 And after a while the brook dried up, because there was no rain in the land.
