A sound, a noise [is] on the mountains, [the] likeness [of] many people! A sound of [the] roar of [the] kingdoms, of nations gathering! Yahweh of hosts [is] mustering an army for battle.

And the king of Assyria sent Rabshakeh from Lachish to Jerusalem, to King Hezekiah, with a large army, and he stood by the conduit of the upper pool on [the] highway of [the] field of [the] washer.

who brings out chariot and horse, army and mighty one. Together they lie down; they cannot rise. They are extinguished, quenched like wick.
