'Evil doer' in the Bible

Before your holy eyes sin may not be seen, and you are unable to put up with wrong; why, then, are your eyes on the false? why do you say nothing when the evil-doer puts an end to one who is more upright than himself?

You went out for the salvation of your people, for the salvation of the one on whom your holy oil was put; wounding the head of the family of the evil-doer, uncovering the base even to the neck. Selah.
