רָנּ֨וּ שָׁמַ֜יִם כִּֽי־עָשָׂ֣ה יְהוָ֗ה הָרִ֙יעוּ֙ תַּחְתִּיּ֣וֹת אָ֔רֶץ פִּצְח֤וּ הָרִים֙ רִנָּ֔ה יַ֖עַר וְכָל־עֵ֣ץ בּ֑וֹ כִּֽי־גָאַ֤ל יְהוָה֙ יַֽעֲקֹ֔ב וּבְיִשְׂרָאֵ֖ל יִתְפָּאָֽר׃ (פ)
諸天哪，要歡唱，因為永恆者已經成就了這事！地的深處啊，要歡呼！眾山哪，要放聲歌唱！森林和其中的各樣樹木啊，也要歌唱！因為永恆者已救贖了雅各，並要因以色列彰顯自己的榮耀。
Ibn Ezra
Sing, 0 ye heavens, etc. This is a figurative expression ; it means: great rejoicing will be through Israel, for through the redemption of Israel the glory of God will be revealed to the whole world.
Tze'enah Ure'enah
“Sing, O heavens” [44:23]. The heavens will sing when God will redeem Israel from the exile in the days of the Messiah. The earth will sing and praise God that the Holy One was very helpful in redeeming them and also the mountains will rejoice and the forest with its trees will sing that God has redeemed Jacob. The Holy One will receive honor from Israel and from the nations who will say that the Holy One performed miracles for Israel. Amen.
