1 Kings 18:5-6

5and Ahab said to Obadiah, Go through the land, to all the fountains of water and to all the torrents, perhaps we may find grass to save the horses and the mules alive, so that we may not have to destroy some of [our] beasts.

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