Go ye forth of Babylon, flee ye from the Chaldeans, with a voice of singing declare ye, tell this, utter it even to the end of the earth; say ye, The LORD hath redeemed his servant Jacob.
Go ye forth of Babylon ... tell this ... to the end of the earth. Primarily a prophecy of their joyful deliverance from Babylon, and a direction that they should leave it when God opened the way. But the publication of it "to the end of the earth," shows it has a more worldwide scope antitypically; Revelation 18:4 shows that the mystical Babylon is ultimately meant.
Redeemed ... Jacob - (Isaiah 43:1; Isaiah 44:22-23.)
