וְהָיָ֗ה בְּי֨וֹם הָנִ֤יחַ יְהוָה֙ לְךָ֔ מֵֽעָצְבְּךָ֖ וּמֵרָגְזֶ֑ךָ וּמִן־הָעֲבֹדָ֥ה הַקָּשָׁ֖ה אֲשֶׁ֥ר עֻבַּד־בָּֽךְ׃
到了永恆者使你脫離愁苦、煩亂，並你被迫所服的苦役，得享安息的那日，
Ibn Ezra
מעצבך From thy hardship. Judah is addressed. מעצבך from thy hardship refers to the sufferings of the body, מרגזך from thy trouble to those of the heart.1This distinction between עצב and רנז can only refer to the relative meaning of these two words, when following each other; but עצב by itself is used also for the trouble of the heart and soul; comp. Gen. 45:5, 1 Sam. 20:34. A. V, From thy sorrow and from thy fear.
Rashi
from your sorrow and from your shuddering which the king of Babylon saddened you and caused you to shudder, and when you see his downfall, you will be eased, since you will go out free.
