'Commander' in the Bible

He has sacrificed oxen and fattened steers and sheep in abundance, and has invited all the king’s sons and Abiathar the priest and Joab the commander of the army [to a feast], but he did not invite your servant Solomon.

For it came about, when David was in Edom, and Joab the commander of the army had gone up to bury those killed [in battle] and had struck down every male in Edom

But when Hadad heard in Egypt that David had died and that Joab the commander of the army was dead, Hadad said to Pharaoh, “Let me leave, so that I may go to my own country.”

and the people who were camped heard it said, “Zimri has conspired and has also struck down the king.” So all Israel made Omri, the commander of the army, king over Israel that day in the camp.
