5 Moreover you know also what Joab the son of Zeruiah did to me, and what he did to the two commanders of the armies of Israel, to Abner the son of Ner and Amasa the son of Jether, whom he killed. And he shed the blood of war in peacetime, and put the blood of war on his belt that was around his waist, and on his sandals that were on his feet. 6 Therefore do according to your wisdom, and do not let his gray hair go down to the grave in peace. 7 But show kindness to the sons of Barzillai the Gileadite, and let them be among those who eat at your table, for so they came to me when I fled from Absalom your brother. 8 And see, you have with you Shimei the son of Gera, a Benjamite from Bahurim, who cursed me with a malicious curse in the day when I went to Mahanaim. But he came down to meet me at the Jordan, and I swore to him by the Lord, saying, 'I will not put you to death with the sword.' 9 Now therefore, do not hold him guiltless, for you are a wise man and know what you ought to do to him; but bring his gray hair down to the grave with blood."
10 So David rested with his fathers, and was buried in the City of David. 11 The period that David reigned over Israel was forty years; seven years he reigned in Hebron, and in Jerusalem he reigned thirty-three years.

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.
