The king throws two of his officers into prison for neglecting their duties. There in prison, they meet the young slave. They each have a strange dream on the same night. That morning they discuss the dreams with the young slave. He interprets their dreams and foretells that one officer will be executed and one will return to his post.
Prison is serious business.

The young slave shaved, changed his clothes and was then brought before the King. Your Majesty's dream foretells seven years of plenty, followed by seven years of famine in the land of Egypt.
