1 Kings 18:3-5

And Ahab called Obadiah, which was the governor of his house. (Now Obadiah feared the LORD greatly: for it was so, when Jezebel cut off the prophets of the LORD, that Obadiah took an hundred prophets, and hid them by fifty in a cave, and fed them with bread and water.) And Ahab said unto Obadiah, Go into the land, unto all fountains of water, and unto all brooks: peradventure we may find grass to save the horses and mules alive, that we lose not all the beasts.
