And it came to pass after these things
After Joseph had been accused and cast into prison, where he had been for some time: [that] the butler of the king of Egypt and [his] baker had offended
their lord the king of Egypt;
committed some fault, at least were accused of one, which raised his displeasure at them. The Targum of Jonathan says, that they consulted to put poison into his drink and food; which, it is not improbable, considering their business and office, they might be charged with; at least it is much more probable than what Jarchi suggests, that the one put a fly into his cup, and the other a little stone or sand into his bread.
