John Gill Commentary 2 Samuel 11:23

"And the messenger said unto David, The men prevailed against us, and came out unto us into the field, and we were upon them even unto the entrance of the gate." — 2 Samuel 11:23 (ASV)

And the messenger said to David
The particulars of his account follow:

surely the men prevailed against us ;
the men of the city of Rabbah, the besieged there, in one onset they made upon them:

the besiegers that lay encamped there; they sallied out upon them:

and we were upon them, even to the entering of the gate ;
rallied upon them, and drove them back, and pursued them to the gate of the city.
