'Wrong doing' in the Bible

Let us therefore leave elementary Christian teaching alone and advance toward maturity. We must not be always relaying foundations, of repentance for wrong-doing, and of faith in God,

For I will be merciful to their wrongdoing,and I will never again remember their sins.

how much more surely will the blood of the Christ, who with the eternal Spirit made himself an unblemished offering to God, purify our consciences from the old wrongdoing for the worship of the everliving God?

For we know God, who said [Deut. 32:35], "Revenge belongs to me; I will pay back [for wrongdoing]." And again [Deut. 32:36], "The Lord will judge His people."
