1 Reis 18:21

How long halt ye between two opinions? — In this exclamation is expressed the very motto of Elijah’s life. It is that of righteous impatience of the “halting” (i.e., limping to and fro) “between two opinions — at all times more dangerous, because more easy, than open apostasy — which was evidently characteristic of Ahab, and probably of the mass of the people. It might have suited well the accommodating genius of such polytheism as had been brought into Israel since the days of Solomon himself, but was utterly incompatible with the sole absolute claim of the worship of Jehovah. Perhaps Jezebel would have scorned it equally for Baal. Compare the indignant expostulation of Ezekiel (Ezequiel 20:31; Ezequiel 20:39). The question, once clearly understood, is always unanswerable, and is listened to here in awestruck silence.
