'Army's' in the Bible

Then Abimelech came to him from Gerar with Ahuzzath, his [close friend and confidential] adviser, and Phicol, the commander of his army.

Therefore this is what the Lord God says: I am going to give the land of Egypt to Nebuchadnezzar king of Babylon, who will carry off its wealth, seizing its spoil and taking its plunder. This will be his army’s compensation.
