Isaiah 8:16-20

16Bind up the testimony, seal the law among my disciples.

17And I will wait for Jehovah, who hideth his face from the house of Jacob; and I will look for him.

18Behold, I and the children that Jehovah hath given me are for signs and for wonders in Israel, from Jehovah of hosts, who dwelleth in mount Zion.

19And when they shall say unto you, Seek unto the necromancers and unto the soothsayers, who chirp and who mutter, [say,] Shall not a people seek unto their 1God? [Will they go] for the living unto the dead?

20To the law and the testimony! If they speak not according to this word, for them there is no daybreak.
