“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.
And they shall pass through it, hardly bestead and hungry: and it shall come to pass, that when they shall be hungry, they shall fret themselves, and curse their king and their God, and look upward. And they shall look unto the earth; and behold trouble and darkness, dimness of anguish; and they shall be driven to darkness.” Isaiah 8:19-22 (KJB)
For the sake of clarity I include the English Standard Version…
“And when they say to you, “Inquire of the mediums and the necromancers who chirp and mutter,” should not a people inquire of their God? Should they inquire of the dead on behalf of the living?
To the teaching and to the testimony! If they will not speak according to this word, it is because they have no dawn.
They will pass through the land, greatly distressed and hungry. And when they are hungry, they will be enraged and will speak contemptuously against their king and their God, and turn their faces upward. And they will look to the earth, but behold, distress and darkness, the gloom of anguish. And they will be thrust into thick darkness.” Isaiah 8:19-22 (ESV)
