displease thee = be evil in thine eyes. This event put David in Joab's power, which Joab freely used. David was not tongue-tied in 2Sa_3:29; but from now he had to endure Joab's insolence, being too suspicious to trust him, and too weak to dismiss him. Compare 2Sa_14:19; 2Sa_19:7. 1Ki_2:5, 1Ki_2:32, 1Ki_2:33.
one as well as another = now this one, now that one.
