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. And they thirsted not when he led them through the deserts: he caused the waters to flow out of the rock for them: he clave the rock also, and the waters gushed out. There is no peace, saith the LORD, unto the wicked.
God called on the godly remnant to go forth from Babylon and joyfully proclaim the Lord as their Redeemer. If Jehovah did it once, He can do it again. The wicked Israelites who refuse to obey the Lord by separating themselves from Babylon, and all it stands for, would never know peace. Part of this statement was fulfilled in the exodus from Egypt.
