I Kings 17:4-6, 14-16

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.

For thus says the LORD God of Israel: ‘The bin of flour shall not be used up, nor shall the jar of oil run dry, until the day the LORD sends rain on the earth.’ ” So she went away and did according to the word of Elijah; and she and he and her household ate for many days. The bin of flour was not used up, nor did the jar of oil run dry, according to the word of the LORD which He spoke by Elijah.
