OET interlinear ISA 27:9

uW Translation Notes:

Note 1 topic: grammar-connect-logic-result

לָ⁠כֵ֗ן

for=so/thus/hence

The term translated as Therefore indicates that what follows is a result of what came before. Use a connector in your language that makes this clear. Alternate translation: [This is why]

Note 2 topic: figures-of-speech / activepassive

יְכֻפַּ֣ר עֲוֺֽן יַעֲקֹ֔ב

atoned_for guilt_of Yaakob

The expression will be covered is a passive verbal form. If it would be unnatural to use that form, you could express the idea in active form or in another way that is natural in your language. If you need to say who does the action, the context indicates that it is Yahweh. Alternate translation: [Yahweh will cover the iniquity of Jacob]

Note 3 topic: figures-of-speech / abstractnouns

עֲוֺֽן

guilt_of

If your language does not use an abstract noun for the idea of iniquity, you could express the same idea in another way. Alternate translation: [the wicked deeds of]

Note 4 topic: figures-of-speech / metaphor

פְּרִ֖י הָסִ֣ר חַטָּאת֑⁠וֹ

fruit(sg) removal its_sin_of,his

Here Isaiah is speaking as if the outcome of removing sin were fruit that a plant produces. Your language may have a comparable expression that you can use in your translation, or you could state the meaning plainly. Alternate translation: [the result of his sin being removed]

Note 5 topic: figures-of-speech / abstractnouns

הָסִ֣ר חַטָּאת֑⁠וֹ

removal its_sin_of,his

If your language does not use an abstract noun for the idea of the removing of his sin, you could express the same idea in another way. Alternate translation: [his sin being removed]

when,makes,he all/each/any/every stones_of altar like,stones_of chalk crushed_to_pieces

The point of this comparison is that just as crushed stones of chalk are easily broken apart, so the stones of the altar will be completely destroyed. If it would be helpful in your language, you could make this point explicitly. Alternate translation: [when he completely destroys all of the stones of the altar, breaking them apart as easily as one can crush chalk]

Note 7 topic: figures-of-speech / activepassive

כְּ⁠אַבְנֵי גִר֙ מְנֻפָּצ֔וֹת
