רָנּ֨וּ שָׁמַ֜יִם כִּֽי־עָשָׂ֣ה יְהוָ֗ה הָרִ֙יעוּ֙ תַּחְתִּיּ֣וֹת אָ֔רֶץ פִּצְח֤וּ הָרִים֙ רִנָּ֔ה יַ֖עַר וְכָל־עֵ֣ץ בּ֑וֹ כִּֽי־גָאַ֤ל יְהוָה֙ יַֽעֲקֹ֔ב וּבְיִשְׂרָאֵ֖ל יִתְפָּאָֽר׃ (פ)
Пой, небеса, ибо Господь это сделал; Кричи, низшие части земли; Начинайте петь, горы, лес и всякое дерево в нем; Ибо Господь искупил Иакова и славит Себя в Израиле.
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.
