I have been wondering for years what is the origin of the Arabic name of Jesus 3iisaa as it is found in the Quran. Without the initial 3ayin it would be easy to say that it derives from the Greek Iesous, as Jesus does. The problem is the initial 3ayin. Where does it come from? The original Hebrew and Aramaic names carry a 3ayin, but at the end not at their beginning. The only linguistically cognate name in the Bible is that of Esau, 3esav in Hebrew, although Esau has nothing to do with Jesus.
