OET interlinear ISA 28:28

uW Translation Notes:

Note 1 topic: writing-pronouns

לֹ֥א & יְדוּשֶׁ֑⁠נּוּ

not & anyone,threshes_it

The pronoun he refers to the farmer, and the pronoun it refers to the grain. It may be helpful to clarify this for your readers. Alternate translation: [the farmer does not thresh the grain forever]

Note 2 topic: figures-of-speech / activepassive

לֶ֣חֶם יוּדָ֔ק

food/grain/bread crushed

The expression is crushed 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. Alternate translation: [A farmer crushes bread grain]

Note 3 topic: figures-of-speech / reduplication

כִּ֛י לֹ֥א לָ⁠נֶ֖צַח אָד֣וֹשׁ יְדוּשֶׁ֑⁠נּוּ

that/for/because/then/when not to,perpetuity go_on anyone,threshes_it

Isaiah is repeating forms of the verb thresh in order to intensify his expression of the idea that it conveys. If your language can repeat words for intensification, it would be appropriate to do that here in your translation. If not, your language may have another way of expressing the intensification. Alternate translation: [although the farmer certainly does not thresh it forever]

Note 4 topic: grammar-connect-logic-contrast

וְ֠⁠הָמַם גִּלְגַּ֧ל עֶגְלָת֛⁠וֹ וּ⁠פָרָשָׁ֖י⁠ו לֹֽא־יְדֻקֶּֽ⁠נּוּ

and,he_sets_in_motion wheel_of his_cart_of,his and,horses_of,his not he,crushes_it

Isaiah uses the word but here to indicate a contrast between drives the wheel of his cart over it and does not crush it. In your translation, indicate this contrast in a way that is natural in your language. Alternate translation: [Although he drives the wheel of his cart over it, his horse does not crush it]
