Isaiah 48:17-19

17This is what the Lord says— your Redeemer, the Holy One of Israel: “I am the Lord your God, who teaches you what is best for you, who directs you in the way you should go.

18If only you had paid attention to my commands, your peace would have been like a river, your well-being like the waves of the sea.

19Your descendants would have been like the sand, your children like its numberless grains; their name would never be blotted out nor destroyed from before me.”
