'Officer' in the Bible

Uriah replied, "The ark, along with Israel and Judah, are encamped in tents, while my commanding officer Joab and my master's staff members are camping out in the open fields. Should I go home, eat, drink, and have sex with my wife? Not on your life! I won't do something like this, will I?"

From the three he was given honor and he became their officer, even though he was not one of the three.
