Hebrews 2:2 confirms that Old Testament punishments were morally just retributions, not merely symbolic — validating the OT penal code as a genuine moral revelation.

Hebrews 2:2 states that every transgression and disobedience under the Mosaic law 'received a just retribution.' The New Testament here provides inspired commentary affirming that all the punishments of the OT law were morally appropriate to their corresponding crimes. This rules out the objection that the law's graded penalties were only typological and had no bearing on the actual moral weight of individual sins.
