Isaiah 30:20-22

New Catholic Bible

²⁰ Although the Lord may give you the bread of adversity
    and the water of affliction,
he who is your Teacher will no longer hide himself,
    but with your own eyes you will see your Teacher.
²¹ And when you stray from your path,
    whether to the right or to the left,
you will hear his voice behind you,
    sounding in your ears and saying,
    “This is the way; continue to follow it.”
²² Then you will realize how unclean
    are your silver-plated idols
    and your gold-plated images.
You will cast them away like polluted rags
    and shout at them, “Away with you!”
