'Army' in the Bible

And it shall be, when thou hearest a sound of marching in the tops of the mulberry-trees, that then thou shalt bestir thyself; for then will Jehovah have gone forth before thee, to smite the army of the Philistines.

But the king's word prevailed against Joab, and against the captains of the army. And Joab and the captains of the army went out from the presence of the king to count the people of Israel.
