Genesis 40:1-3, 14, 23

Some time later, Pharaoh’s chief cup-bearer and chief baker offended their royal master. Pharaoh became angry with these two officials, and he put them in the prison where Joseph was, in the palace of the captain of the guard.

And please remember me and do me a favor when things go well for you. Mention me to Pharaoh, so he might let me out of this place.

Pharaoh’s chief cup-bearer, however, forgot all about Joseph, never giving him another thought.
