Isaiah 8:18-20 English Standard Version Anglicised (ESVUK)
18 Behold, I and the children whom the Lord has given me are signs and portents in Israel from the Lord of hosts, who dwells on Mount Zion. 19 And when they say to you, “Enquire of the mediums and the necromancers who chirp and mutter,” should not a people enquire of their God? Should they enquire of the dead on behalf of the living? 20 To the teaching and to the testimony! If they will not speak according to this word, it is because they have no dawn.
