'Forgiveness of Sins' in the Bible

But so that you may see that on earth the Son of man has authority for the forgiveness of sins, (then said he to the man who was ill,) Get up, and take up your bed, and go to your house.

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.
