On the third day, as Joseph had said, the prophecy lands. The Targum reports it with ceremonial quietness. It was on the third day, the nativity of Pharoh that he made a feast to all his servants. And he lifted up the head of the chief butler, and the head of the chief baker, in the midst of his servants (Genesis 40:20).
Pseudo-Jonathan, redacted in the Land of Israel in the early common era, uses the phrase yoma de-geneisa — the day of his nativity — a term that later rabbinic literature associates with pagan festivals (see Avodah Zarah 8a). Pharaoh's birthday is a court occasion. Favors are granted. Grudges are settled. And in front of the assembled servants, the king performs the two acts of public judgment that Joseph had already seen in the interpretations of the dreams.
The Aramaic keeps the grim pun of the Hebrew. The king lifts up the head of both prisoners, in a single sentence — restoring one to his office, removing the other from his body. Bereshit Rabbah 88 hears in the parallelism a lesson about power: the same sovereign, on the same day, at the same feast, hands out reward and death with the same gesture. The decision was not the king's, really. It was already in the dreams.
Notice how the Torah structures the verification. The dreams were interpreted in private in a prison cell. The verification happens in public, at the palace, in front of the whole court. Joseph has no way of confirming what the guards report back from the feast — but the record of his accuracy is now permanent in the memory of every servant who was there. Chief among them, of course, is the butler who has just been restored to his post.
The Sages read this verse as the moment heaven seals Joseph's credentials, not in Joseph's view but in Egypt's. Two years will still have to pass. The butler will forget him. But when Pharaoh's own dream later troubles him (Genesis 41:1-8), there will be a man in the court who, one day, will remember a morning in prison when the interpretation of the dream was exactly right.
The takeaway is about how vindication actually works. Often the truth you spoke in a closed room is confirmed in a public ceremony you do not attend. Heaven, the Targum teaches, has its own timing for letting a record stand up and speak for you.
