Genesis 40

While in prison, Joseph interprets the dreams of two of Pharaoh's officials: the chief cupbearer and the chief baker. Joseph correctly prophesies that the cupbearer will be restored to his position in three days, but that the baker will be executed. Joseph asks the cupbearer to remember him and mention him to Pharaoh. Three days later, the prophecies come true exactly as predicted. However, the chief cupbearer, upon his restoration, forgets all about Joseph and his service for two full years.
