'Cup bearer' in the Bible
After these things happened, the cupbearer to the king of Egypt and the royal baker offended their master, the king of Egypt.
Pharaoh was enraged with his two officials, the cupbearer and the baker,
Both of them, the cupbearer and the baker of the king of Egypt, who were confined in the prison, had a dream the same night. Each man's dream had its own meaning.
So the chief cupbearer told his dream to Joseph: "In my dream, there was a vine in front of me.
In three more days Pharaoh will reinstate you and restore you to your office. You will put Pharaoh's cup in his hand, just as you did before when you were cupbearer.
On the third day it was Pharaoh's birthday, so he gave a feast for all his servants. He "lifted up" the head of the chief cupbearer and the head of the chief baker in the midst of his servants.
He restored the chief cupbearer to his former position so that he placed the cup in Pharaoh's hand,
But the chief cupbearer did not remember Joseph -- he forgot him.
Then the chief cupbearer said to Pharaoh, "Today I recall my failures.
Please, O Lord, listen attentively to the prayer of your servant and to the prayer of your servants who take pleasure in showing respect to your name. Grant your servant success today and show compassion to me in the presence of this man." Now I was cupbearer for the king.
