5 Now you have knowledge of what Joab, the son of Zeruiah, did to me, and to the two captains of the army of Israel, Abner, the son of Ner, and Amasa, the son of Jether, whom he put to death, taking payment for the blood of war in time of peace, and making the band of my clothing and the shoes on my feet red with the blood of one put to death without cause. 6 So be guided by your wisdom, and let not his white head go down to the underworld in peace. 7 But be good to the sons of Barzillai the Gileadite, and let them be guests at your table; for so they came to me when I went in flight from Absalom your brother. 8 Now you have with you Shimei, the son of Gera the Benjamite of Bahurim, who put a bitter curse on me on the day when I went to Mahanaim; but he came down to see me at Jordan, and I gave him my oath by the Lord, saying, I will not put you to death by the sword. 9 But do not let him be free from punishment, for you are a wise man; and it will be clear to you what you have to do with him; see that his white head goes down to the underworld in blood.

Commentary on 1 Kings 2:5-11
(Read 1 Kings 2:5-11)
These dying counsels concerning Joab and Shimei, did not come from personal anger, but for the security of Solomon's throne, which was the murders he had committed, but would readily repeat them to carry any purpose; though long reprieved, he shall be reckoned with at last. Time does not wear out the guilt of any sin, particularly of murder. Concerning Shimei, Hold him not guiltless; do not think him any true friend to thee, or thy government, or fit to be trusted; he has no less malice now than he had then. David's dying sentiments are recorded, as delivered under the influence of the Holy Ghost, 2 Samuel 23:1-7. The Lord discovered to him the offices and the salvation of that glorious personage, the Messiah, whose coming he then foretold, and from whom he derived all his comforts and expectations. That passage gives a decided proof that David died under the influence of the Holy Ghost, in the exercise of faith and hope.
