Judges 21:9

For the people were numbered
To know who did come up, and who did not, and particularly to know whether the inhabitants of Jabeshgilead did or not, against whom an information was brought:

and, behold, there were none of the inhabitants of Jabeshgilead there;
for as yet none that came had returned home; all came to Shiloh first, to pay their devotion to the Lord; and as none were found among the living, it did not appear they were among the slain; and very probably the muster roll was taken before they went to battle, and they were not on that.
