1 Kings 17:13-16

ISV(i) 13 But Elijah told her, “You can stop being afraid. Go and do what you said, but first make me a muffin and bring it to me. Then make a meal for yourself and for your son, 14 because this is what the LORD God of Israel says: ‘That jar of flour will not run out, nor will that bottle of oil become empty until the very day that the LORD sends rain on the surface of the ground.’”
15 So she went out and did precisely what Elijah told her to do. As a result, Elijah, the widow, and her son were fed for days. 16 The jar of flour never ran out and the bottle of oil never became empty, just as the LORD had promised through Elijah.
