Albert Barnes Commentary 1 Kings 18:26

"And they took the bullock which was given them, and they dressed it, and called on the name of Baal from morning even until noon, saying, O Baal, hear us. But there was no voice, nor any that answered. And they leaped about the altar which was made." — 1 Kings 18:26 (ASV)

And called on the name of Baal from morning until noon - Compare the parallel in the conduct of the Greeks of Ephesus (Acts 19:34). The words O Baal, hear us, probably floated on the air as the refrain of a long and varied hymn of supplication.

They leaped upon the altar which was made - The marginal rendering is preferable to this. Wild dancing has always been a devotional exercise in the East, and remains so to this day; witness the dancing dervishes. It was practiced especially in the worship of Nature-powers, like the Dea Phrygia (Cybele), the Dea Syra (Astarte?), and the like.
