19:4-7 At times we must reprove those in authority over us. Joab knew he was risking the king’s displeasure by confronting him, but he saw what had to be done. Joab told David that there would be dreadful consequences if he didn’t commend the troops for their victory. Joab’s actions are a helpful example to us when personal confrontation is necessary.
19:8 David sat at the town gate because that was where business was conducted and judgment rendered. His presence there showed that he was over his mourning and back in control.
19:8-10 Just a few days before, most of Israel was supporting the rebel ruler Absalom. Now the people wanted David back as their king. Because crowds are often fickle, there must be a higher moral code to follow than the pleasure of the majority. Following the moral principles given in God’s Word will help you avoid being swayed by the popular opinions of the crowd.
19:11-12 Why was the tribe of Judah hesitant to bring David back as king? Apparently the elders of Judah had consented to Absalom’s rebellion. It is not surprising that leaders who had backed Absalom would hesitate before inviting David back.
19:13 David’s appointment of Amasa was a shrewd political move. First, Amasa had been commander of Absalom’s army; by making Amasa his commander, David would secure the allegiance of the rebel army. Second, by replacing Joab as commander in chief, David punished him for his previous crimes (3:26-29). Third, Amasa had a great deal of influence over the leaders of Judah (19:14). All of these moves would help to unite the kingdom.
19:19, 20 By admitting his wrong and asking David’s forgiveness, Shimei was trying to save his own life. His plan worked for a while. This was a day of celebration, not execution. But we read in 1 Kings 2:8, 9 that David advised Solomon to execute Shimei.
19:21ff David showed tremendous mercy and generosity as he returned to Jerusalem. He spared Shimei, restored Mephibosheth, and rewarded faithful Barzillai. David’s fairness sets a standard for government that will be fully realized in Christ’s righteous rule in the coming Kingdom.
