1 Kings 18:7-10

7And as Obadiah was in the way, behold, Elijah met him: and he knew him, and fell on his face, and said, Is it thou, my lord Elijah? 8And he answered him, It is I: go, tell thy lord, Behold, Elijah is here. 9And he said, Wherein have I sinned, that thou wouldest deliver thy servant into the hand of Ahab, to slay me? 10As Jehovah 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 here, he took an oath of the kingdom and nation, that they found thee not.
