'Army' in the Bible

Yahweh thunders his voice before his army; for his forces are very great; for he is strong who obeys his command; for the day of Yahweh is great and very awesome, and who can endure it?

But I will remove the northern army far away from you, and will drive it into a barren and desolate land, its front into the eastern sea, and its back into the western sea; and its stench will come up, and its bad smell will rise." Surely he has done great things.

I will restore to you the years that the swarming locust has eaten, the great locust, the grasshopper, and the caterpillar, my great army, which I sent among you.
