V.1-4 What wonderful words for us all to apply to our life. What God here promises to do to Solomon, He will do to you too, but it requires obedience to God. Let Him prove it!
V.5-9 David had shown mercy to Joab and Shimei, but these two men did not repent, so their punishment is to be settled by wise Solomon. And as David remembered their bad acting, he also remembered the kindness of Barzillai (2 Sam. 19:31-38).
V.13-25 No repentance no blessing! Adonijah knew who God’s choice was (v. 15), but instead of personally going to Solomon to humble himself in confession, he sends the king’s mother to try to get a favor for himself.
V.26-27 Abiathar’s faithfulness to David is not forgotten. But Abiathar had not continued with God’s choice instead he had sided with Adonijah (1 Kings 1:7), and now he loses his favored place as priest.
V.28-35 Joab had been the general of David’s army, but he had not acted according to the desires of the king.
V.36-46 A simple way to avoid death, but after three years Shimei no longer remembers the king’s words. This cost him his life. These two chapters are strong reminders that our life is going to be reviewed before God.
