And they slew them - None ever more richly deserved death; and by this act of justice, David showed to all Israel that he was a decided enemy to the destruction of Saul's family; and that none could lift up their hands against any of them without meeting with condign punishment. In all these cases I know not that it was possible for David to show more sincerity, or a stricter regard for justice.

Cut off their hands … - After they were dead. Their hands and feet were hung up in a place of public resort, both to deter others and also to let all Israel know that David was not privy to the murder of Ish-bosheth.

A person may be glad to obtain his just wishes, and yet really regret the means by which he receives them. He may be sorry for the death of a person by which he is a gainer. These men shed innocent blood, from the basest motives. David justly executed vengeance upon them. He would not be beholden to any to help him by unlawful practices. God had helped 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 many storms yet before him, he knew that He who had delivered, would deliver.
