Isaiah 8:19–20

When someone tells you to consult mediums and spiritists, who whisper and mutter, should not a people inquire of their God? Why consult the dead on behalf of the living? Consult God’s instruction and the testimony of warning. If anyone does not speak according to this word, they have no light of dawn.

When they say to you, “Inquire of the mediums and the spiritists who chirp and mutter,” shouldn’t a people inquire of their God? Should they inquire of the dead on behalf of the living? Go to God’s instruction and testimony! If they do not speak according to this word, there will be no dawn for them.

Someone may say to you, “Let’s ask the mediums and those who consult the spirits of the dead. With their whisperings and mutterings, they will tell us what to do.” But shouldn’t people ask God for guidance? Should the living seek guidance from the dead?

Look to God’s instructions and teachings! People who contradict his word are completely in the dark.

Now if they tell you, “Consult the ghosts and the spirits, those who chirp and those who mutter. Should not a people consult its gods, the dead on behalf of the living, for teaching and for testimony?” surely they who speak like this have no dawn.

And when they shall say unto you, Seek unto them that have familiar spirits,

And unto wizards that peep, and that mutter:

Should not a people seek unto their God?

For the living to the dead?

To the law and to the testimony:

If they speak not according to this word,

It is because there is no light in them.
