The Rabbis held that G-d had given Noah seven commandments embracing the whole of natural religion: against (i) idol worship, (ii) blasphemy, (iii) bloodshed, (iv) adultery, (v) robbery, (vi) for the establishment of courts of justice, (vii) against eating the limb torn off a living animal. These were imposed on all men, Jews and non-Jews alike.
