Exodus 34:29-35 tells that after meeting with God the skin of Moses' face became radiant, frightening the Israelites and leading Moses to wear a veil. Jonathan Kirsch, in his book Moses: A Life, thought that, since he subsequently had to wear a veil to hide it, Moses' face was disfigured by a sort of "divine radiation burn".
This passage has led to one longstanding tradition that Moses grew horns. This is derived from a misinterpretation of the Hebrew phrase karan `ohr panav (קָרַן עֹור פָּנָיו). The root קרן Q-R-N (qof, resh, nun) may be read as either "horn" or "ray [of light]", depending on vocalization. `Ohr panahv (עֹור פָּנָיו) translates to "the skin of his face".[84]
Interpreted correctly, these two words form an expression meaning that Moses was enlightened, that "the skin of his face shone" (as with a gloriole), as the KJV has it.[
