Following are a number of back-translations of John 7:19:
Uma: “The prophet Musa long ago gave you the Law of the Lord. But there is not one of you who follows that Law. Why do you want to kill me?'” (Source: Uma Back Translation)
Yakan: “Isa said also to those leaders, ‘Did Musa not give to you the law? But none of you follows the law. Why do you want to kill me?'” (Source: Yakan Back Translation)
Western Bukidnon Manobo: “Our ancestor long ago Moses, he is the one who gave you the laws, and I know that there is none of you who fulfills the law, for why are you thinking about killing me?'” (Source: Western Bukidnon Manobo Back Translation)
Kankanaey: “Moses is the one who made-known to you God’s law back then, isn’t that so? But absolutely none of you obeys-it. Because if you did obey it, you wouldn’t be-intending to kill-me.'” (Source: Kankanaey Back Translation)
Tagbanwa: “Isn’t it so that it was Moises who gave you the laws? But no matter who of you, there’s really no truth/reality to your following/obeying of those laws. If your following really was true, why would you want to kill me?'” (Source: Tagbanwa Back Translation)
Tenango Otomi: “Isn’t it true that Moses gave you the law? And that law is what no one of you has obeyed. How come you want to kill me because you say that I don’t obey what the law says?'” (Source: Tenango Otomi Back Translation)
Like many languages (but unlike Greek or Hebrew or English), Tuvan uses a formal vs. informal 2nd person pronoun (a familiar vs. a respectful “you”). Unlike other languages that have this feature, however, the translators of the Tuvan Bible have attempted to be very consistent in using the different forms of address in every case a 2nd person pronoun has to be used in the translation of the biblical text.
As Voinov shows in Pronominal Theology in Translating the Gospels (in: The Bible Translator 2002, p. 210ff.), the choice to use either of the pronouns many times involved theological judgment. While the formal pronoun can signal personal distance or a social/power distance between the speaker and addressee, the informal pronoun can indicate familiarity or social/power equality between speaker and addressee.
Here, Jesus is addressing his disciples, individuals and/or crowds with the formal pronoun, showing respect.
In most Dutch translations, Jesus addresses his disciples and common people with the informal pronoun, whereas they address him with the formal form.
The name that is transliterated as “Moses” in English is signed in Spanish Sign Language in accordance with the depiction of Moses in the famous statue by Michelangelo (see here). (Source: John Elwode in The Bible Translator 2008, p. 78ff.)
Another depiction in Spanish Sign Language (source: Carlos Moreno Sastre):
The horns that are visible in Michelangelo’s statue are based on a passage in the Latin Vulgate translation (and many Catholic Bible translations that were translated through the 1950ies with that version as the source text). Jerome, the translator, had worked from a Hebrew text without the niqquds, the diacritical marks that signify the vowels in Hebrew and had interpreted the term קרו (k-r-n) in Exodus 34:29 as קֶ֫רֶן — keren “horned,” rather than קָרַו — karan “radiance” (describing the radiance of Moses’ head as he descends from Mount Sinai).
Even at the time of his translation, Jerome likely was not the only one making that decision as this recent article alludes to.
