2 Samuel 19:6
In that thou lovest thine enemies, and hatest thy friends. For thou hast declared this day, that thou regardest neither princes nor servants: for this day I perceive, that if Absalom had lived, and all we had died this day, then it had pleased thee well.
The words are Joab's sharp rebuke to David when the king's grief over Absalom became so excessive that it put to shame the very soldiers who had risked their lives to save him and his household. David was shut away mourning for his rebellious son instead of acknowledging the victory that had preserved his throne, his life, and his family. Joab confronted him directly over this failure, treating the mourning as a public dishonor to loyal men returning from battle.
The charge was that David was acting as if he loved his enemies and hated his friends, weeping for the one who had sought his overthrow while slighting those who had stood by him. In doing so he seemed to show no regard for either princes or servants, for commanders or common soldiers alike. The rebuke pressed further that David appeared to wish Absalom had lived even if all his faithful supporters had died in his place that day. Stung by this plain speaking, David rose and went out to sit in the gate and speak encouragingly to the troops, restoring their honor and confidence.
