'Army' in the Bible

The Lord utters His voice before His army;Surely His camp is very great,For strong is he who carries out His word.The day of the Lord is indeed great and very awesome,And who can endure it?

“But I will remove the northern army far from you,And I will drive it into a parched and desolate land,And its vanguard into the eastern sea,And its rear guard into the western sea.And its stench will arise and its foul smell will come up,For it has done great things.”

“Then I will make up to you for the yearsThat the swarming locust has eaten,The creeping locust, the stripping locust and the gnawing locust,My great army which I sent among you.
