28. But if they be not converted, do you at least repent, who by many a slip have fallen from the lofty pinnacle of innocence and faith. We have a good Lord, Whose will it is to forgive all, Who called you by the prophet, and said: “I, even I, am He that blotteth out transgressions, and I will not remember, but do thou remember, and let us plead together.” Isa. xliii. 25 [LXX.]. St. Ambrose, taking the Septuagint reading, makes the contrast to be between man’s remembering and God’s forgetting. But the contrast in the Hebrew is different: God will do away sins of His pure mercy and challenges Israel to bring forward any merits which can plead for pardon. God shows that His mercy is even greater than His justice. St. Ambrose, as is shown more clearly in chap. vi., is merely using a verbal antithesis.
