1 Kings 17:13-16

13And Elijah said unto her, Fear not; go and do as thou hast said: but make me thereof a little cake first, and bring it forth unto me, and afterward make for thee and for thy son.

14For thus saith the LORD, the God of Israel, The barrel of meal shall not waste, neither shall the cruse of oil fail, until the day that the LORD sendeth rain upon the earth.

15And she went and did according to the saying of Elijah: and she, and he, and her house, did eat many days.

16The barrel of meal wasted not, neither did the cruse of oil fail, according to the word of the LORD, which he spake by Elijah.
