1 Kings 18:24

And call ye on the name of your gods
The Baalim, the many lords and gods they served:

and I will call on the name of the Lord;
the one true Jehovah and God of Israel, whom I serve:

and the God that answereth by fire;
by causing fire to come down upon the sacrifice, and consume it:

let him be God;
accounted, owned, and acknowledged as the true God, and so afterwards worshipped as such:

and all the people answered and said, it is well spoken;
they thought it a very reasonable proposal, a very good method to determine the controversy, and come at the truth, and know who was the true God, and who not.
