If - the king's wrath arise - It is likely that Joab had by some indiscretion suffered loss about this time;; and he contrived to get rid of the odium by connecting the transaction with the death of Uriah, which he knew would be so pleasing to the king.

And if so be that the king's wrath arise,.... Which might be seen in his countenance, or expressed in his words:

and he say, wherefore approached ye so nigh unto the city when ye did fight? as to expose the king's troops to the enemy on the wall, who by stones or darts greatly annoyed them, or sallied out on them, and killed many of them:

knew ye not that they would shoot from the wall? they must have known that, and therefore should have kept out of the reach of their shot.

And if so be that the king's wrath arise, and he say unto thee, Wherefore approached ye so nigh unto the city when ye did fight? knew ye not that they would shoot from the wall?

11:14-27 Adulteries often occasion murders, and one wickedness is sought to be covered by another. The beginnings of sin are much to be dreaded; for who knows where they will end? Can a real believer ever tread this path? Can such a person be indeed a child of God? Though grace be not lost in such an awful case, the assurance and consolation of it must be suspended. All David's life, spirituality, and comfort in religion, we may be sure were lost. No man in such a case can have evidence to be satisfied that he is a believer. The higher a man's confidence is, who has sunk in wickedness, the greater his presumption and hypocrisy. Let not any one who resembles David in nothing but his transgressions, bolster up his confidence with this example. Let him follow David in his humiliation, repentance, and his other eminent graces, before he thinks himself only a backslider, and not a hypocrite. Let no opposer of the truth say, These are the fruits of faith! No; they are the effects of corrupt nature. Let us all watch against the beginnings of self-indulgence, and keep at the utmost distance from all evil. But with the Lord there is mercy and plenteous redemption. He will cast out no humble, penitent believer; nor will he suffer Satan to pluck his sheep out of his hand. Yet the Lord will recover his people, in such a way as will mark his abhorrence of their crimes, to hinder all who regard his word from abusing the encouragements of his mercy.
