Adam Clarke on Acts 13:8

But Elymas, the sorcerer, (for so is his name by interpretation) - That is, Elymas is the interpretation of the word μαγος, or sorcerer; not of the word Bar-Jesus as some have imagined; and to support which they have been led into strange etymologies on the word βαρ-Ιησους, Bar-Jesus. But how is Elymas, Ελυμας, the interpretation of the word μαγος, magician or sorcerer? Ans. Both names are Asiatic; but neither Hebrew nor Greek. I have already observed, in the note on Mat 2:1, that mogh in Persian means an idolater, a worshipper of fire, and sometimes what we term a magician. Elymas is from the Arabic ilm, knowledge, science, doctrine, art; from alama, he was wise, skilled, etc.; hence aleem or alymon, a doctor or learned man, and, with the Greek termination, ελυμας, Elymas, the interpretation of mogh, Greek μαγος, magos, a magician, a wise man, doctor, etc.
