Later, Romeo stumbles into the secluded garden under Juliet's bedroom balcony and the two exchange impassioned pledges. They are soon secretly married by Romeo's confessor and father figure, Friar Laurence, with the assistance of Juliet's nursemaid. Unfortunately, another street duel breaks out between Juliet's first cousin Tybalt and Romeo's best friend Mercutio when Tybalt insults Romeo.

The film consists of five main sections: The Creation, Adam and Eve, Cain and Abel, Noah's Ark, and the story of Abraham. There are also a pair of shorter sections, one recounting the building of the Tower of Babel, and the other the destruction of Sodom and Gomorrah. The sections vary greatly in tone. The story of Abraham is somber and reverential, while that of Noah repeatedly focuses on his love of all animals—herbivorous and carnivorous or omnivorous. Cats (including lions) drink milk, with Noah's relationship with the animals being depicted harmoniously. It was originally conceived as the first in a series of films retelling the entire Old Testament, but these sequels were never made.
