What is the etymology of name 'Isa?

I was doing some research on the name of Prophet Jesus p.b.u.h. The wikipedia mentions: "There is a major discrepancy between the Hebrew/Aramaic and Muslim Arabic forms of this name, since the Hebrew form of this name has the voiced pharyngeal ʿAyin ע‎ or ʿAyn ع consonant at the end of the name (as does Christian Arabic يسوع yasūʿ), while the Muslim Arabic form عيسى ʿīsā has the ʿAyn at the beginning of the name." And: "Scholars have been puzzled by the use of ʿĪsā in the Qur'an since Christians in Arabia used yasūʿ before and after Islam". Can anyone guide me on this issue. I'm having questions thatWhy quran used 'Isa if christians of Arabia used to call him as yasu' and why quranic version has ع in the beginning etc.
