The dissemination of the law is presented in the fourth compartments on the south and north walls, both painted by Rosselli. In the Moses cycle we see him receiving the tables of the Law on Mount Sinai. On the opposite wall is the Sermon on the Mount. The Sermon on the Mount is filled with masses of people. The twelve disciples huddle close together behind Christ and to the right. Farther back we see them approaching with their master. On the right side Christ is seen healing a leper.
