1 Kings 17:1, 7, 15

And Elijah the Tishbite, who was of the inhabitants of Gilead, said unto Ahab, As the LORD God of Israel liveth, before whom I stand, there shall not be dew nor rain these years, but according to my word.

And it came to pass after a while, that the brook dried up, because there had been no rain in the land.

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