John Gill's Bible Commentary Ver. 9. Now therefore hold him not guiltless , etc.] Do not look upon him as an innocent person; and if he commits an offence against thee, as he has against me, do not acquit him as I have done: for thou [art] a wise man ; so it seems he was before the appearance of the Lord to him at Gibeon, even before his father’s death he had given some proofs of it to David himself: and knowest what thou oughtest to do unto him ; to watch and observe him, and, if found offending, to punish him according to the rules of justice, and the laws of the land: but his hoary head bring thou down to the grave with blood ; spare him not on account of his age, but put him to death whensoever he shall be found guilty, let him not die a natural death.
Matthew Henry Commentary
Verses 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 an purpose; though long reprieved, he shall be reckoned with at last. Tim does not wear out the guilt of any sin, particularly of murder Concerning Shimei, Hold him not guiltless; do not think him any tru friend to thee, or thy government, or fit to be trusted; he has no les malice now than he had then. David's dying sentiments are recorded, a delivered under the influence of the Holy Ghost, 2Sa 23:1-7. The Lor 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 decide proof that David died under the influence of the Holy Ghost, in the exercise of faith and hope.
