I Kings 18:36 15 And Elijah said, As the LORD of hosts liveth, before whom I stand, I will surely shew myself unto him to day.
16 So Obadiah went to meet Ahab, and told him: and Ahab went to meet Elijah.
17 And it came to pass, when Ahab saw Elijah, that Ahab said unto him, Art thou he that troubleth Israel?And it came to pass at the time of the offering of the evening sacrifice, that Elijah the prophet came near, and said, LORD God of Abraham, Isaac, and of Israel, let it be known this day that thou art God in Israel, and that I am thy servant, and that I have done all these things at thy word.

37 Hear me, O LORD, hear me, that this people may know that thou art the LORD God, and that thou hast turned their heart back again.
