Isaiah 48:20-21

Go ye forth from 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, Jehovah 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.
