Have ye not known? have ye not heard? hath it not been told you from the beginning? have ye not understood from the foundations of the earth?
Have ye not know? - who worship idols. The question emphatically implies they had known.
From the beginning - (Isaiah 41:4; Isaiah 41:26; Isaiah 48:16.) God is the beginning (Revelation 1:8). The tradition handed down from the very first, of the creation of all things by God at the beginning, ought to convince you of His omnipotence, and of the folly of idolatry.
