Charles Ellicott Commentary 2 Samuel 11:9

"But Uriah slept at the door of the king`s house with all the servants of his lord, and went not down to his house." — 2 Samuel 11:9 (ASV)

At the door of the king’s house. —Probably in the guard chamber at the entrance of the palace. (Compare to 1 Kings 14:27–28.) It is quite unnecessary to suppose that Uriah had any suspicion of what had been done. His conduct and language are simply that of a brave, frank, generous-hearted soldier.
