(15) Retire ye from him.--This part of David's orders was not carried out. Perhaps Joab thought it would make the stratagem too evident, or perhaps it was impracticable. At all events, the consequence was that others were slain with Uriah, and thus a larger blood-guiltiness fell upon David.

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.And he wrote in the letter, saying,.... Giving the following orders to Joab:

set ye Uriah is the forefront of the hottest battle: over against that part of the city where the enemy was strongest, and the battle the fiercest, and the stones and arrows were cast the thickest:

and retire ye from him; leave him to himself to combat the enemy alone; who seeing him deserted, would sally out upon him, and the few that might be with him, and slay him:

that he may be smitten, and die; thus he sought to add murder to adultery, and that in the basest manner, and which he accomplished; and this is often the case, that murder follows adultery, either by way of revenge for it, or in order to cover it, as here.
