Observed the city - In the sense of besieging it closely.

And it came to pass, when Joab observed the city,.... Where lay its greatest strength, and where it was best defended; or besieged it, as the Targum:

that he assigned Uriah unto a place where he knew that valiant men were; who would not easily give way, and when they saw an opportunity would sally out, Joab cannot be excused from sin, unless he thought that Uriah had been guilty of death, and that David took this way of dispatching him for some political reason; however David was king, and to be obeyed.

The king's wishes were fully carried out by Joab. "When Joab watched (i.e., blockaded) the city, he stationed Uriah just where he knew that there were brave men" (in the city).

And it came to pass, when Joab observed the city, that he assigned Uriah unto a place where he knew that valiant men were.

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.
