1 Kings 17:10

So he, Elijah, arose, and went to Zarephath. And when he came to the gate of the city, behold, the widow woman was there gathering of sticks, Elijah recognizing her as a widow either by her clothes or by the fact that she was engaged in this lowly task. And he called to her, to find out whether she were the woman of whom the Lord had spoken, and said, Fetch me, I pray thee, a little water in a vessel that I may drink, the vessel being his own drinking-cup, which he had carried with him from the land of Israel.
