מוסר אויף בראשית 41:39

The word אחד, one, again figures prominently when Joseph interpreted Pharaoh's dream in 41,25. Joseph's rise to power was due to his interpreting Pharaoh's dream as "one." In the dream of the seven ears of corn the Torah emphasized that they all grew on "one" stalk (41, 22). Even the dream of the seven cows alluded to the number "one," since the cows all rose from "one" river. Considering the above factors, we can now understand the comment of Pharaoh that there was no one as נבון וחכם, wise and clever as Joseph. Pharaoh said to Joseph: "After G–d has made known to you, i.e. הודיע, all this, etc.," you clearly command all three elements of wisdom, namely חכמה, בינה, דעת.

Pharaoh told Joseph that he saw G–d had revealed to him, Joseph, the secret of how חכמה and בינה can be joined by דעת, and that there was no one else who had been so endowed. Although Pharaoh personally was quite unaware of these "secrets," he expressed profound truths through his mouth. He was able to do so because his representative in the Celestial Regions had an understanding of these matters and put these words in his mouth.
