Matthew Poole and continuators on Judges 21:3

3 And said, O LORD God of Israel, Why is this come to pass in Israel, that there should be to day one tribe lacking in Israel ?

Why hast thou given them up to such wickedness, and us to such rage, that the whole Tribe should be in a manner lost! Hence it appears, that they did not swear to root them all out, as is further manifest from the different matter and words of this Oath, ver. 1. which only denied them their Daughters in Marriage; and that concerning the people of other Tribes who joyned not with them in this business, which was, that they should be put to death, v. 5. And their sparing of those 600 Men in the Rock Rimmon, v. 13, 14. plainly shews, that they were not obliged by any Oath or Vow to extirpate them.
