Moses is important in JUDAISM, not Buddhism. Moses plays no part in Buddhism and his moral perspective is one that generally deals with creating a better society in this world than the Buddhist perspective, which is primarily about realizing and accepting the broken-ness and unsatisfactory-ness of this world.
