OET interlinear DEUT 17:16

uW Translation Notes:

Note 1 topic: grammar-connect-logic-contrast

רַק֮

only

Moses uses the word Only here to indicate a strong contrast between what is allowed and not allowed for Israel’s king. In your translation, indicate this strong contrast in a way that is natural in your language. Alternate translation: [But]

לְמַ֖עַן הַרְבּ֣וֹת ס֑וּס

to acquire_many horses

This could mean that the king must not (1) send people to Egypt to buy horses for him as is modeled in the UST, or (2) sell Israelites to the Egyptians in exchange for horses. Alternate translation: [in exchange for horses for him]

Note 2 topic: figures-of-speech / quotesinquotes

וַֽ⁠יהוָה֙ אָמַ֣ר לָ⁠כֶ֔ם לֹ֣א תֹסִפ֗וּ⁠ן לָ⁠שׁ֛וּב בַּ⁠דֶּ֥רֶךְ הַ⁠זֶּ֖ה עֽוֹד

and=YHWH he/it_had_said to/for=you(pl) not you(pl),will_repeat to,return (Some words not found in UHB: only not acquire_many for=him/it horses and=not cause_~_to_return DOM the,people to,Egypt to acquire_many horses and=YHWH he/it_had_said to/for=you(pl) not you(pl),will_repeat to,return on,way the=this again/more )

If it would be clearer in your language, you could translate this so that there is not a quotation within a quotation, as modeled by the UST.

Note 3 topic: figures-of-speech / explicitinfo

לֹ֣א תֹסִפ֗וּ⁠ן לָ⁠שׁ֛וּב בַּ⁠דֶּ֥רֶךְ הַ⁠זֶּ֖ה עֽוֹד

not you(pl),will_repeat to,return (Some words not found in UHB: only not acquire_many for=him/it horses and=not cause_~_to_return DOM the,people to,Egypt to acquire_many horses and=YHWH he/it_had_said to/for=you(pl) not you(pl),will_repeat to,return on,way the=this again/more )

The expression no longer return that way again contains extra information that would be unnatural to express in some languages. If this is true of your language, you could shorten the expression. Alternate translation: [You will not return that way]
