But now, this is what the Lord, your Creator says, O Jacob,And He who formed you, O Israel,“Do not fear, for I have redeemed you [from captivity];I have called you by name; you are Mine!

“Everyone who thirsts, come to the waters;And you who have no money come, buy grain and eat.Come, buy wine and milkWithout money and without cost [simply accept it as a gift from God].
