'Commander' in the Bible

Now at that time Abimelech and Phicol, the commander of his army, said to Abraham, “God is with you in everything you do;

So they made a covenant at Beersheba; then Abimelech and Phicol, the commander of his army, got up and returned to the land of the Philistines.

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