Matthew Poole and continuators on 1 Kings 2:9

9 Now therefore hold him not guiltless : for thou art a wise man , and knowest what thou oughtest to do unto him , but his hoar head bring thou down to the grave with blood .

Though I have desired his life, do not treat him as an innocent Person, neither let him go wholly unpunished.

And therefore wiltst easily find out just occasions to chastise him, especially considering his perverse and wicked disposition.

How to punish him, not without just cause, and yet without any violation of my Oath, or reflection upon me, or upon Religion for my or thy sake.

i. e. With the effusion of his blood, with a bloody or violent death.
