OET interlinear ISA 62:9

uW Translation Notes:

Note 1 topic: grammar-connect-logic-contrast

כִּ֤י מְאַסְפָי⁠ו֙ יֹאכְלֻ֔⁠הוּ וְ⁠הִֽלְל֖וּ אֶת יְהוָ֑ה וּֽ⁠מְקַבְּצָ֥י⁠ו יִשְׁתֻּ֖⁠הוּ בְּ⁠חַצְר֥וֹת קָדְשִֽׁ⁠י

that/for/because/then/when [those_of,who]_gather_it they,will_eat_it and,they_will_praise DOM YHWH and,[those_of,who]_gather_it they,will_drink_it in,the_courts_of my_holiness_of,my

Isaiah uses the word For here to indicate a contrast between what Yahweh said would no longer happen, that enemies would consume the harvest, and what will happen instead, that those who gather the harvest will eat and drink it themselves. In your translation, indicate this contrast in a way that is natural in your language. Alternate translation: [Instead, its collectors will eat it and praise Yahweh, and its gatherers will drink it in the courts of my holiness]

Note 2 topic: figures-of-speech / abstractnouns

בְּ⁠חַצְר֥וֹת קָדְשִֽׁ⁠י

in,the_courts_of my_holiness_of,my

If your language does not use an abstract noun for the idea of holiness, you could express the same idea in another way. Alternate translation: [in my holy courts]
