'Army' in the Bible

Then I came to the governors beyond the River, and gave them the king's letters. Now the king had sent with me captains of the army and horsemen.

He spoke before his brothers and the army of Samaria, and said, "What are these feeble Jews doing? Will they fortify themselves? Will they sacrifice? Will they finish in a day? Will they revive the stones out of the heaps of rubbish, since they are burned?"

You are Yahweh, even you alone. You have made heaven, the heaven of heavens, with all their army, the earth and all things that are on it, the seas and all that is in them, and you preserve them all. The army of heaven worships you.
