1 Kings 18:8

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

As the LORD thy God liveth, there is no nation or kingdom, whither my lord hath not sent to seek thee: and when they said, He is not there; he took an oath of the kingdom and nation, that they found thee not.
