Isaiah 8:18-20

Darby Translation

¹⁸ Behold, 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.

¹⁹ And 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 God? [Will they go] for the living unto the dead?

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