Potiphar's two eunuchs, butler and baker, offend him and are imprisoned
Genesis 40: 1-3
1 After this, it came to pass, that two eunuchs, the butler and the baker of the king of Egypt, offended their lord. 2 And Pharao being angry with them (now the one was chief butler, the other chief baker), 3 He sent them to the prison of the commander of the soldiers, in which Joseph also was prisoner.
