‘And it happened on the third day, being Pharaoh's birthday, that he made a feast for all his servants and he lifted up the head of the chief cupbearer and the head of the chief baker among his servants, and he restored the chief cupbearer to his cupbearing again and he gave the cup into Pharaoh's hand. But he hanged the chief baker as Joseph had interpreted to them. Yet the chief cupbearer did not remember Joseph, but forgot him.'
It was commonplace for prisoners to be released on the birthday of some great monarch. It was thus a time of much hope for many prisoners. But Joseph was in prison for a private ‘crime' and may thus have been unknown to those who decided such things. However, the chief cupbearer and the chief baker were taken from the prison and brought before the king. The one was fully restored, suggesting either that his innocence had been proved or that his offence had been a minor one, but the chief baker was hung, possibly after being decapitated. ‘Hung' may be a shortened form to cover the whole of what Joseph had forecast.
“His servants.” These would be the highest officials in the land who were ‘the slaves of Pharaoh'.
Joseph probably lived in hope for some time but eventually his hopes died. He was not to know that God yet had a purpose in it. It would be another two years before anything further happened, and meanwhile he went on with his life in prison without much hope of release. The darkest hour often comes before the dawn.
