'Forgiveness of Sins' in the Bible

for this is My blood of the [new and better] covenant, which [ratifies the agreement and] is being poured out for many [as a substitutionary atonement] for the forgiveness of sins.

and that repentance [necessary] for forgiveness of sins would be preached in His name to all the nations, beginning from Jerusalem.

All the prophets testify about Him, that through His name everyone who believes in Him [whoever trusts in and relies on Him, accepting Him as Savior and Messiah] receives forgiveness of sins.”
