Bible Verses About Sin: Alone can forgive

Who keepest mercy unto thousands: who takest away iniquity, and wickedness, and sin, and no man of himself is innocent before thee. Who renderest the iniquity of the fathers to the children, and to the grandchildren unto the third and fourth generation.

But to thee, the Lord our God, mercy and forgiveness, for we have departed from thee:

Who is a God like to thee, who takest away iniquity, and passest by the sin of the remnant of thy inheritance? he will send his fury in no more, because he delighteth in mercy.

Why doth this man speak thus? He blasphemeth. Who can forgive sins, but God only?
