For he hath made him to be sin for us – Τον μη γνοντα ἁμαρτιαν, ὑπερ ἡμων ἁμαρτιαν εποιησεν· He made him who knew no sin, (who was innocent), a sin-offering for us. The word ἁμαρτια occurs here twice: in the first place it means sin, i.e. transgression and guilt; and of Christ it is said, He knew no sin, i.e. was innocent; for not to know sin is the same as to be conscious of innocence; so, nil conscire sibi, to be conscious of nothing against one’s self, is the same as nulla pallescere culpa, to be unimpeachable.
