'Purge' in the Bible

The hand of the witnesses shall be the first against him to put him to death, and afterward the hand of all the people. So you shall remove the evil from among you.

The man who acts presumptuously and insolently by not listening to the priest who stands there to serve the Lord your God, nor to the judge, that man shall die; so you shall remove the evil from Israel.

So shall you remove the guilt of innocent blood from among you, when you do what is right in the sight of the Lord.

“If a man is intimate with a woman who is another man’s wife, they shall both be put to death, the man who lay with the woman, and the woman. So you shall remove the evil from Israel.
