'Armies' in the Bible

When you go out to war against other nations, and come face to face with horses and war-carriages and armies greater in number than yourselves, have no fear of them: for the Lord your God is with you, who took you up out of the land of Egypt.

And it shall be, when the officers have made an end of speaking unto the people, that they shall make captains of the armies to lead the people.

If in war a town is shut in by your armies for a long time, do not let its trees be cut down and made waste; for their fruit will be your food; are the trees of the countryside men for you to take up arms against them?

Your towns will be shut in by his armies, till your high walls, in which you put your faith, have come down: his armies will be round your towns, through all your land which the Lord your God has given you.
