OET interlinear ISA 42:4

uW Translation Notes:

Note 1 topic: grammar-connect-time-sequential

עַד

until

Here, the word until indicates the point in time up to which what Yahweh has just said about Isaiah remains true. Your language may have a connecting phrase that you can use to show this. Alternate translation: [this will continue to when he sets justice on the earth, and the coastlands will wait for his law]

Note 2 topic: figures-of-speech / abstractnouns

עַד־יָשִׂ֥ים בָּ⁠אָ֖רֶץ מִשְׁפָּ֑ט

until established on_the=earth justice

If your language does not use an abstract noun for the idea of justice, you could express the same idea in another way. Alternate translation: [until he ensures that rulers govern fairly on the earth]

Note 3 topic: figures-of-speech / metaphor

לֹ֤א יִכְהֶה֙ וְ⁠לֹ֣א יָר֔וּץ

not grow_faint and=not discouraged

Here Yahweh is speaking of Isaiah as if he were a flame or a reed that could become dim or be crushed, as in the previous verse. Your language may have a comparable expression that you can use in your translation, or you could state the meaning plainly. Alternate translation: [He will not give up, and no one will stop him]

Note 4 topic: figures-of-speech / metonymy

וּ⁠לְ⁠תוֹרָת֖⁠וֹ אִיִּ֥ים יְיַחֵֽילוּ

and,for,instruction_of,his coastlands wait

Here, coastlands represents “the earth.” If it would be helpful in your language, you could use an equivalent expression or plain language. Alternate translation: [and the earth will wait for his law]
