Genesis - Chapter 40

Joseph is in prison, and in a miraculous way he is going to end up in front of the pharaoh.  Two of pharaoh's servants were put in the same prison as Joseph, and  Joseph correctly interprets their dreams.  The servants are the chief baker and the chief cupbearer, and their dreams are about bread and wine.

This gives us a link to the story of Jesus.  At the end of his ministry on earth Jesus shares the Passover meal with his disciples (the last supper) and tells them that the bread represents his body and the wine represents his blood.

The fact that the servants are the baker and the cupbearer and the dreams are about bread and wine  shows us that Jesus is at the centre of this story.
