📖 Biblical Definition
Joab, son of David’s sister Zeruiah, was commander of David’s army — effective in war but ruthless and politically scheming. His name marks four notorious killings. He murdered Abner at Hebron, in revenge for Abner’s self-defense killing of his brother Asahel (2 Samuel 3:27). He killed Absalom against David’s order (2 Samuel 18:14). He arranged Uriah the Hittite’s death by abandoning him on the front line at David’s order (2 Samuel 11:14-17). He treacherously stabbed Amasa, his replacement, at Gibeon (2 Samuel 20:9-10). He backed Adonijah’s coup at the end. Solomon, on David’s deathbed instructions, executed him at the horns of the altar (1 Kings 2:28-34). The blood of his kingdom-building eventually reached his own house.

Joab — David's nephew and general, ruthless and indispensable.

Joab's loyalty to David was real but always entangled with self-interest. He won battles, organized cover-ups, killed rivals, rebuked the king when needful, and finally backed Adonijah over Solomon. David's deathbed charge to Solomon was that his hoar head should not go down to the grave in peace.

Either lionized as loyal soldier or dismissed as villain; the costly entanglement is missed.
