Charles Ellicott Commentary Jeremiah 51:48

"Then the heavens and the earth, and all that is therein, shall sing for joy over Babylon; for the destroyers shall come unto her from the north, saith Jehovah." — Jeremiah 51:48 (ASV)

Then the heaven and the earth ... —The prophet, following Isaiah (Isaiah 44:23), thinks of the whole creation as rejoicing in the righteous judgment of Jehovah on the guilty city, and in the liberation of His people. They sing, as it were, their Te Deum over the fall of Babylon under the attack of the Medo-Persian armies “from the North.”
