Genesis 40:1-3, 14, 23

Some time later, both Pharaoh’s chief steward and chief baker deeply offended their master, the king of Egypt. Pharaoh was angry with his two officers, the chief steward and the chief baker, so he incarcerated them in the palace of Potiphar, the captain of the guard, in the same prison where Joseph was bound.

When things start to go well for you, remember me, and please be kind and mention me to Pharaoh so that he might release me from here.

but the chief steward completely forgot about Joseph and never remembered him.
