Matthew Poole and continuators on Judges 20:46

46 So that all which fell that day of Benjamin, were twenty and five thousand men that drew the sword: all these were men of valour.

Besides the odd hundred expressed ver. 35. but here only the great number is expressed, the less being omitted, as inconsiderable; which way of numbring is frequent in Scripture, as Iudg. 11. 26. 2 Sam. 5. 5. and in other Authors, and in vulgar use; as when they are called, the 70 Interpreters, who in truth and exactness were 72. Here are also a thousand more omitted, because here he speaks onely of them who fell in that third day of Battel. See on v. 15.
