John Gill's Bible Commentary Ver. 8. And they brought the head of Ishbosheth unto David to Hebron , etc.] Supposing it would have been a very acceptable present to him: and said to the king, behold the head of Ishbosheth the son of Saul thine enemy, which sought thy life ; all which, his relation to Saul, his enmity to David, and his designs upon his life, are artfully put together to raise the indignation of David against him, and make their present of his head to him the more agreeable: and the Lord hath avenged my lord the king this day of Saul and of his seed ; for all the evils and injuries they had done him; this being the last of the sons of Saul by a lawful wife, the two remaining were by a concubine; and these men impiously ascribe to the Lord what they with wicked hands had done.
Matthew Henry Commentary
Verses 8-12 - A person may be glad to obtain his just wishes, and yet really regre the means by which he receives them. He may be sorry for the death of person by which he is a gainer. These men shed innocent blood, from the basest motives. David justly executed vengeance upon them. He would no be beholden to any to help him by unlawful practices. God had helpe him over many a difficulty, and through many a danger, therefore he depended upon him to crown and complete his own work. He speaks of his redemption from all adversity, as a thing done; though he had man storms yet before him, he knew that He who had delivered, woul deliver _________________________________________________
