1 Kings 18:5-9

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.

And as Obadiah was in the way, behold, Elijah met him: and he knew him, and fell on his face, and said, Art thou that my lord Elijah?

And he answered him, I am: go, tell thy lord, Behold, Elijah is here.

And he said, What have I sinned, that thou wouldest deliver thy servant into the hand of Ahab, to slay me?
