John Gill's Bible Commentary Ver. 9. But Uriah slept at the door of the king’s house, with all the servants of his lord , etc.] The bodyguards, which were placed there to watch the palace in the night season; Uriah first fell into a conversation with these as is highly probable, to whom he was well known, and who might inquire of one and another of their friends in the army; and he being weary, laid himself down among there, and slept: and went not down to his house ; whether the trifling questions David asked him, or the information the guards might give him of his wife being sent for to court; made him suspect something, and so had no inclination to go to this own house; or however so it was ordered by the providence of God, which directed him to act in this manner, that the sin of David and Bathsheba they studied to hide might be discovered.
Matthew Henry Commentary
Verses 6-13 - Giving way to sin hardens the heart, and provokes the departure of the Holy Spirit. Robbing a man of his reason, is worse than robbing him of his money; and drawing him into sin, is worse than drawing him into an wordly trouble whatever.
