'Captains' in the Bible

[Ishbosheth], Saul's son, [had] two men who were captains of bands: the name of the one was Baanah, and the name of the other Rechab, the sons of Rimmon the Beerothite, of the children of Benjamin (for Beeroth also is reckoned to Benjamin:

David numbered the people who were with him, and set captains of thousands and captains of hundreds over them.

The king commanded Joab and Abishai and Ittai, saying, "Deal gently for my sake with the young man, even with Absalom." All the people heard when the king commanded all the captains concerning Absalom.

These are the names of the mighty men whom David had: Josheb Basshebeth a Tahchemonite, chief of the captains; the same was Adino the Eznite, against eight hundred slain at one time.

Notwithstanding, the king's word prevailed against Joab, and against the captains of the army. Joab and the captains of the army went out from the presence of the king, to number the people of Israel.
