כִּֽי־בְשִׂמְחָ֣ה תֵצֵ֔אוּ וּבְשָׁל֖וֹם תּֽוּבָל֑וּן הֶהָרִ֣ים וְהַגְּבָע֗וֹת יִפְצְח֤וּ לִפְנֵיכֶם֙ רִנָּ֔ה וְכָל־עֲצֵ֥י הַשָּׂדֶ֖ה יִמְחֲאוּ־כָֽף׃
װאָרום מיט שִׂמחה װעט איר אַרױסגײן, און בשלום װעט איר געפֿירט װערן; די בערג און די הײכןװעלן אױסברעכן פֿאַר אײַך אין געזאַנג, -און אַלע בײמער פֿון פֿעלדװעלן קלאַפּן די הענט.
Tze'enah Ure'enah
“You shall leave in joy, etc.” [55:12]. If you will be pious, then you will go out of the exile with joy. You will be carried to the land of Israel with peace and the hills will sing and dance for you, out of great joy that you are coming to the land. All the trees will rejoice for you, like a person who claps his hands out of joy.
Ibn Ezra
For you shall go out with joy. You will go out from the exile joyfully.
Rashi
the mountains and the hills shall burst into song before you for they will give you their fruit and their plants, and their inhabitants shall derive benefit. ([Some editions read:] And their inhabitants shall sing.)
