Genesis 40:22

Within three more days, Pharaoh will lift up your head from off you, and will hang you on a tree; and the birds will eat your flesh from off you.”

On the third day, which was Pharaoh’s birthday, he made a feast for all his servants, and he lifted up the head of the chief cup bearer and the head of the chief baker among his servants.

He restored the chief cup bearer to his position again, and he gave the cup into Pharaoh’s hand;

Yet the chief cup bearer didn’t remember Joseph, but forgot him.
