'Forgiveness of Sins' in the Bible

To give knowledge of salvation to his people, through the forgiveness of sins,

And he went into all the surrounding region of the Jordan, preaching a baptism of repentance for the forgiveness of sins,

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

And those who were seated at table with him said to themselves, Who is this who even gives forgiveness of sins?

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