'Army' in the Bible

A day of darkness and gloom, a day of cloud and thick darkness, like the dawn spreads on the mountains, a great and strong army! There has been nothing like it from old, and after it nothing will be again {for generations to come}.

like [the] sound of chariots on the tops of the mountains, they leap about; like [the] sound of a flame of fire devouring stubble; like a strong army arranged in rows [for] battle.

And Yahweh {utters} his voice before his army, because his encampment [is] very large; strong [is the] one who carries out his decree, for great [is] the day of Yahweh and exceedingly fearful. Who can endure it?
