Then David gathered all the people together, and went out against Rabbath: and after fighting, he took it.

And David collected all the people, and went to Rabbah, and fought against it, and took it.

And David gathereth all the people, and goeth to Rabbah, and fighteth against it, and captureth it;

Then David got all the people together and went to Rabbah and made war on it and took it.

And so David gathered together all the people, and he set out against Rabbah. And after he had fought, he seized it.

And David gathered all the people together,.... The soldiers that were with him, or near him; which was done partly to recruit Joab's troops, who, by the continuance of the siege, and the sallies of the enemy on them, might be greatly diminished; and partly to make conquests of other cities of the Ammonites, and to carry off the spoil of them:
and went to Rabbah; which must be after the death of Uriah, and very probably during the time of Bathsheba's mourning for him:
and fought against it, and took it; by assault.

Accordingly David "gathered together all the people," - i.e., all the men of war who had remained behind in the land; from which we may see that Joab's besieging army had been considerably weakened during the long siege, and at the capture of the water-city, - "and fought against the acropolis, and took it."
