Judges 21:3

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, Judges 21:1, which only denied them their daughters in marriage; and that concerning the people of other tribes who joined not with them in this business, which was, that they should be put to death, Judges 21:5. And their sparing of those six hundred men in the rock Rimmon, Judges 21:13,14, plainly shows that they were not obliged by any oath or vow to extirpate them.
