 The Greek for for sins is either huper ( G5228) or peri ( G4012) hamartion ( G266) . It so happens that in the Greek version of the Old Testament the regular phrase for a sin-offering is peri ( G4012) hamartias ( G266) (Hamartias, G266, is the singular of hamartion, G266) , as, for instance, in Leviticus 5:7 and Leviticus 6:30. That is to say, Peter is laying it down that the death of Christ is the sacrifice which atones for the sin of men.
