1 Kings 18:5-6

5 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.
6 So they divided the land between them to pass throughout it: Ahab went one way by himself, and Obadiah went another way by himself.
