The Animated Stories from the Book of Mormon (1987)

Mahonri, the brother of Jared, is a righteous man in wicked Babel. After the tower of Babel is destroyed and the language of the people is confused, the Lord shows Mahonri how to build barges to carry the righteous across the sea to the Promised Land. When the brother of Jared asks the Lord to touch stones to light the barges, his faith is so strong that he receives a great revelation.
