Isaiah 8:18-20 21st Century King James Version (KJ21)
18 Behold, I and the children whom the Lord hath given me are for signs and for wonders in Israel from the Lord of hosts, who dwelleth in Mount Zion.
19 And when they shall say unto you, “Seek unto those who have familiar spirits and wizards, who peep and who mutter,” should not a people seek unto their God? For the living, to the dead?
20 To the law and to the testimony! If they speak not according to this word, it is because there is no light in them.
