1 Kings 18:36-37

36At the time of the evening sacrifice, Elijah the prophet approached the altar and said, “O LORD, God of Abraham, Isaac, and Israel, let it be known this day that You are God in Israel and that I am Your servant and have done all these things at Your command. 37Answer me, O LORD! Answer me, so that this people will know that You, the LORD, are God, and that You have turned their hearts back again.”
