Isaiah 8:18-20 Amplified Bible, Classic Edition (AMPC)
18 Behold, I and the children whom the Lord has given me are [a]signs and wonders [that are to take place] in Israel from the Lord of hosts, Who dwells on Mount Zion.
19 And when the people [instead of putting their trust in God] shall say to you, Consult for direction mediums and wizards who chirp and mutter, should not a people seek and consult their God? Should they consult the dead on behalf of the living?
20 [Direct such people] to the teaching and to the testimony! If their teachings are not in accord with this word, it is surely because there is no dawn and no morning for them.
Isaiah 8:18-20 New International Version (NIV)
18 Here am I, and the children the Lord has given me. We are signs and symbols in Israel from the Lord Almighty, who dwells on Mount Zion.
The Darkness Turns to Light
19 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? 20 Consult God’s instruction and the testimony of warning. If anyone does not speak according to this word, they have no light of dawn.
