'Armies' in the Bible

And David became greater and greater in power, because the Lord of armies was with him.

Then when he went back to Ziklag, there came over to him, of the men of Manasseh, Adnah and Jozabad and Jediael and Michael and Jozabad and Elihu and Zillethai, captains of thousands from the armies of Manasseh.

So now, say to my servant David, The Lord of armies says, I took you from the fields, from keeping sheep, so that you might be a ruler over my people Israel;

So let your words be made certain and your name be made great, when men say, The Lord of armies is the God of Israel; and when the family of David your servant is made strong before you.
