Isaiah 8:17

14 And he will be for a holy place: but for a stone of falling and a rock of trouble to the two houses of Israel, and to the men of Jerusalem, for a net in which they may be taken.

15 And numbers of them, falling on the stone, will be broken, and will be taken in the net.

16 Let my teaching be kept secret: and my words be given to my disciples only.

17 And I will be waiting for the Lord, whose face is veiled from the house of Jacob, and I will be looking for him.

18 See, I and the children whom the Lord has given me, are for signs and for wonders in Israel from the Lord of armies, whose resting-place is in Mount Zion.

19 And when they say to you, Make request for us to those who have control of spirits, and to those wise in secret arts, who make hollow bird-like sounds; is it not right for a people to make request to their gods, to make request for the living to the dead?

20 Then say to them, Put your faith in the teaching and the witness. ... If they do not say such things. ... For him there is no dawn. ...
