'Commander' in the Bible

Adonijah has sacrificed myriads of oxen, fattened cattle, and sheep, and he has invited all of the king's sons, Abiathar the priest, and Joab the commander of the army, but he has not invited your servant Solomon.

The LORD will repay him for his bloodshed because, without my father David's consent he attacked and murdered two men more righteous and better than he, Ner's son Abner, the commander of Israel's army and Jether's son Amasa, commander of Judah's army.

During David's military campaign against Edom, when his army commander Joab had gone out to bury the dead, he killed every male in Edom.

Later on, Hadad learned in Egypt that David had been buried with his ancestors and that Joab the army commander was dead. So Hadad asked Pharaoh, "Please send me out so I can go back to my own land."

The army at the encampment heard this report: "Zimri has conspired against the king and killed him." So the entire army of Israel made Omri, their commander, king over Israel.
