1 Kings 18:2-6

And Elijah went to shew himself unto Ahab. And there was a sore famine in Samaria.

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.

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