Matthew Poole and continuators on Judges 20:15

15 And the children of Benjamin were numbred at that time out of the city, twenty and six thousand men that drew sword; beside the inhabitants of Gibeah, which were numbred seven hundred chosen men .

Object. This agrees not with the following numbers: for all that were slain of Benjamin were 25100 men, v. 35. and there were only 600 that survived, v. 47. which make only 25700. Ans. The other thousand men were either left in some of their cities, where they were slain, v. 48. or were cut off in the two first Battels, wherein it is unreasonable to think they had an unbloody Victory: and as for these 25100 men, they were all slain in that day, i. e. the day of the third Battel, as is affirmed v. 35.
