You have no idea what is in the New Covenant. You sit in judgement as if you were God Himself. Satan is the accuser of the brethren. Lord Jesus said, "Let him who is without sin throw the first stone".That was not part of the law of Moses.
It was teaching concerning the righteous and is still applicable today in the New Covenant.
You'd be right if this was something the Lord gave under the Law of Moses, but you're not because it's not.
