'Army' in the Bible

Though an army encamp against me, my heart will not fear. Though war arise against me, [even] in this I [will] remain confident.

The king [is] not saved by [the] greatness of an army. The warrior is not delivered by [the] greatness of strength.

But he tossed Pharaoh and his army into [the] {Red Sea}, for his loyal love [endures] forever.
