Destroy in anger; destroy so they are no more, so that they may know that God [is] ruling in Jacob to the ends of the earth. Selah

But by whom may the day of his coming be faced? and who may keep his place when he is seen? for he is like the metal-tester's fire and the cleaner's soap.

There is only one Lawgiver and Judge the one who can save and destroy. So who are you to judge your neighbor?
