'Offender' in the Bible

Therefore, though I wrote to you, it was not to punish the offender, nor to secure justice for him who had suffered the wrong, but it was chiefly in order that your earnest feeling on our behalf might become manifest to yourselves in the sight of God.

For He who said, "Do not commit adultery," also said, "Do not commit murder," and if you are a murderer, although not an adulterer, you have become an offender against the Law.
