And they dreamed a dream both of them, each man his dream in one night, each man according to the interpretation of his dream, the butler and the baker of the king of Egypt, which were bound in the prison. (Genesis 40:5)
The striking similarity of their dreams convinced the two men that the dreams were in some way related to their fate, but just how they knew not. Knowing, no doubt, that their cases might be decided any day, and being deprived in prison of professional dream interpreters, they were obviously anxious the next morning when Joseph entered their room.
