'Mutilated' in the Bible

"'You must not present to the Lord something blind, or with a broken bone, or mutilated, or with a running sore, or with a festering eruption, or with a feverish rash. You must not give any of these as a gift on the altar to the Lord.

So they yelled louder and, in accordance with their prescribed ritual, mutilated themselves with swords and spears until their bodies were covered with blood.
