The butler and baker give Joseph the standard complaint of prisoners in an ancient city. They have dreamed, and there is no court interpreter available in their cell. The Targum preserves Joseph's reply in its clean, theological form. Are not the interpretations of dreams from the Lord? Tell it now to me (Genesis 40:8).
Pseudo-Jonathan, redacted in the Land of Israel in the early common era, is recording one of the most elegant theological claims in the Joseph story. The palace of Pharaoh had a whole guild of professional chartumim, interpreters of dreams (Genesis 41:8) — priests trained in the reading of omens, equipped with manuals and techniques. Egypt believed dream interpretation was a craft, a learned technology. Joseph disagrees, in one sentence. The craft is real; the source is not in Egypt. Pitronin me-Adonai inun — interpretations are from the Lord.
Bereshit Rabbah 89 hears the confidence in Joseph's follow-up: tell it now to me. He is not saying he is gifted. He is saying that if the meaning belongs to God, and God is accessible, the reading is possible. The interpreter is not a magician; he is a listener. Joseph will listen to the dream and listen, at the same time, for the voice that put it there.
This becomes the structural claim that will carry Joseph into the palace. When Pharaoh will later summon him, Joseph will repeat the exact formula: It is without me; it is not man who interprets dreams: but from before the Lord shall be an answer of peace unto Pharaoh (Genesis 41:16). The Egyptian court has a guild; Joseph has a source.
The Sages teach that Joseph's sentence is also a critique of dream-guilds of every kind. A reading without a connection to truth is a technique looking for a customer. Joseph's way is the opposite: reduce the interpreter, honor the source, speak plainly, take no credit.
The takeaway is old. The gifts we think we have are almost always rentals. The interpretations we offer others are borrowed light. When we remember whose they are, they arrive with more accuracy. When we forget, we become one more professional in a long corridor of guesses.
