Genesis 40:1-3, 14, 23

Now some time later, the cupbearer (butler) and the baker for the king of Egypt offended their lord, Egypt’s king. Pharaoh (Sesostris II) was extremely angry with his two officials, the chief of the cupbearers and the chief of the bakers. He put them in confinement in the house of the captain of the guard, in the same prison where Joseph was confined.

Only think of me when it goes well with you, and please show me kindness by mentioning me to Pharaoh and get me out of this house.

Yet [even after all that] the chief cupbearer did not remember Joseph, but forgot [all about] him.
