OET interlinear HAG 1:10

uW Translation Notes:

Note 1 topic: figures-of-speech / personification

כָּלְא֥וּ שָמַ֖יִם מִ⁠טָּ֑ל וְ⁠הָ⁠אָ֖רֶץ כָּלְאָ֥ה יְבוּלָֽ⁠הּ

(Some words not found in UHB: on/upon/above/on_account_of//he/it_went_in yes/correct/thus/so on,you(pl) withheld heavens from,dew and=the=earth withheld produce_of,its )

Yahweh is speaking as if the heavens and the earth were living things that could actively withhold dew and produce from the Judeans. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: [there is no dew from the heavens above you and there is no produce from the earth]

Note 2 topic: figures-of-speech / explicit

עֲלֵי⁠כֶ֔ם כָּלְא֥וּ שָמַ֖יִם מִ⁠טָּ֑ל

on,you(pl) (Some words not found in UHB: on/upon/above/on_account_of//he/it_went_in yes/correct/thus/so on,you(pl) withheld heavens from,dew and=the=earth withheld produce_of,its )

Yahweh is speaking as if dew fell from the heavens, that is, from the sky. He means implicitly that not only has rain not been falling from the sky, dew has not even been forming on the ground overnight. You could indicate that in your translation if it would be helpful to your readers. Alternate translation: [not only has it not been raining, dew has not even been forming,]
