'Commander' in the Bible

Now David said, “Whoever strikes down a Jebusite first shall be chief and commander.” Joab the son of Zeruiah [David’s half sister] went up first, and so he was made chief.

When the Arameans (Syrians) saw that they had been defeated by Israel, they sent messengers and brought out the Arameans who were beyond the [Euphrates] River, with Shophach the commander of the army of Hadadezer leading them.

But the Arameans fled before Israel, and David killed of the Arameans 7,000 charioteers and 40,000 foot soldiers, and put to death Shophach the commander of the army.

The third commander of the army for the third month was Benaiah, the son of Jehoiada the priest, as chief; and in his division were 24,000.

Ahithophel was succeeded by Jehoiada the son of Benaiah and by Abiathar; and Joab was the commander of the king’s army.
