Judaism also stressed forgiveness, though some teachers saw the need to limit forgiveness to three instances of premeditated sin, pointing out that repentance was otherwise not genuine (ARN 40A). But Jesus here reverses the principle of 490-fold (compare Gen 4:24 LXX) or seventy-sevenfold (Gen 4:24, where LXX uses the exact phrase; Carson 1984:405) vengeance, demanding unlimited forgiveness toward the truly repentant.
