1 Kings 18:19

Send — Messengers, that this controversy may be decided, what is the cause of these heavy judgments. All Israel — By their heads, or representatives, that they may be witnesses of all our transactions. Carmel — Not that Carmel, in Judah, but another in Issachar by the midland sea, which he chose as a convenient place being not far from the center of his kingdom, to which all the tribes might conveniently resort, and at some distance from Samaria, that Jezebel might not hinder. Prophets of Baal — Who were dispersed in all the parts of the kingdom. Of the groves — Who attended upon those Baal's or idols that were worshipped in the groves, which were near the royal city, and much frequented by the king and the queen.
