[Just mythoughts]

"Your confusion about the meaning of the word Kohen is just one example of how significant meanings can be lost in translation. Another, very famous mistranslation, is of the word amah in Isaiah chapter 7."

No my confusion is not about the meaning of the word, that word does not specifically mean Levi. Anybody can claim to be a priest does not make them from the tribe of Levi. Which goes back to what the point was to begin with that when Ezra and Nehemiah left Babylon the Levities had turnover their duty in the Temple to the Nethinims who were not of Levi.

No my confusion is not about the meaning of the word

Your confusion goes way beyond not understanding the meaning of one word. Your confusion is caused by not having a freaking clue.
