uW Translation Notes:

Note 1 topic: figures-of-speech / you

וְ⁠אַ֣נְתְּ עֶזְרָ֗א

and,you ˊEzrāʼ

Connecting Statement:

The king now returns to address Ezra personally, so you refers to him here, and is singular, The three instances of your in this verse are also singular, as is the verb appoint. Only the phrase you shall teach is plural, referring to Ezra and to those whom he will appoint. If your language distinguishes between levels of social status, the form for a superior addressing a respected individual would be appropriate.

Note 2 topic: figures-of-speech / abstractnouns

כְּ⁠חָכְמַ֨ת אֱלָהָ֤⁠ךְ דִּֽי־בִ⁠ידָ⁠ךְ֙

according_to,wisdom god,your that/who in/on/at/with,hand,you

If your language does not use abstract nouns such as wisdom, you can express that idea in a different way. Alternate translation: “because the law of your God has made you wise” or “guided by the wise teachings of your God that you know so well”

Note 3 topic: figures-of-speech / metaphor

דִּֽי־בִ⁠ידָ⁠ךְ֙

that/who in/on/at/with,hand,you

Most likely, the phrase that is in your hand here means the same thing as in 7:14, where the law of God is described as being in Ezra's hand. Review the note there if that would be helpful. As there, the phrase in your hand here could mean: (1) that Ezra knows it and uses it with great ability. Alternate translation: “that you know and use well” or (2) that Ezra personally owns a scroll of God's wisdom. Alternate translation: “that you have with you”

Note 4 topic: figures-of-speech / doublet

מֶ֣נִּי שָׁפְטִ֞ין וְ⁠דַיָּנִ֗ין דִּי־לֶהֱוֺ֤ן דאנין

appoint magistrates and,judges that/who they_may_be judge

The terms magistrates and judges mean very similar things. There are two possibilities here. (1) Artaxerxes could be using these two terms to refer to people in slightly different roles. The first term may refer to officials who decide disputes between people, and the second term may refer to officials who interpret the law and apply it to specific situations. Alternate translation: “appoint officials who can decide disputes between people and officials who can interpret and apply the law” or (2) Artaxerxes may be using the two words together to emphasize the authority that Ezra has to ensure that the Jews in Judah and Jerusalem follow God’s commandments. If you have only one term for these functions, you can just use that one term here. Alternate translation: “appoint judges so that they can judge”

Note 5 topic: figures-of-speech / explicit

לְ⁠כָל־עַמָּ⁠ה֙ דִּ֚י בַּ⁠עֲבַ֣ר נַהֲרָ֔⁠ה לְ⁠כָל־יָדְעֵ֖י דָּתֵ֣י אֱלָהָ֑⁠ךְ

to/from=all/each/any/every people,the that/who in/on/at/with,province_beyond river,the to/from=all/each/any/every know laws god,your

The second phrase clarifies the meaning of the first phrase, showing that Artaxerxes is referring specifically to the Jews who live in this province. He is allowing the Jews there to have their own legal system, based on the law of Moses. If it would be helpful in your language, you could say that explicitly. Alternate translation: “all the Jews living in Beyond-the-River province, who know the laws of your God”

Note 6 topic: figures-of-speech / you

וְ⁠דִ֧י לָ֦א יָדַ֖ע תְּהוֹדְעֽוּן

and,who not knowing teach

The word you here is plural. If your language distinguishes between forms of you, the form for a superior addressing a group of people would be appropriate.

Note 7 topic: figures-of-speech / explicit

וְ⁠דִ֧י לָ֦א יָדַ֖ע תְּהוֹדְעֽוּן

and,who not knowing teach

The implication, in light of the plural you, is that Ezra and the judges he appoints are to teach the law of God to any Jews living in the province who are not familiar with it, so that they can follow it. Alternate translation: “And I want you and the judges to teach the law of God to those Jews in the province who do not know it.”
