The noise of a multitude in the mountains, like as of a great people; a tumultuous noise of the kingdoms of nations gathered together: the LORD of hosts mustereth the host of the battle.

A loud sound of many people in the mountains, like a huge crowd; a big noisy group of countries coming together: the powerful Lord gathers the army for the fight.
