John Gill Commentary 2 Samuel 11:7

"And when Uriah was come unto him, David asked of him how Joab did, and how the people fared, and how the war prospered." — 2 Samuel 11:7 (ASV)

And when Uriah was come to him
To David, to whom he came first, before he went to his own house, desirous of knowing what was the special business of the king with him:

David asked him how Joab was doing, and how the people were doing, and how
the war was prospering ;
he asked about the welfare of Joab the general, and of the common soldiers, and of the warriors, as the Targum, the mighty men that went along with Joab, (2 Samuel 10:7) (11:1) . David seems to have been at a loss what to say to him. These questions were so mean and trivial, that it might justly give Uriah some suspicion that it could never be on this account, that he was sent for; since David could not want intelligence of such things, messengers were daily sent to him.
