My people are destroyed for lack of knowledge. Because you have rejected knowledge, I will also reject you, That you may be no priest to me. Because you have your God's law, I will also forget your children.
"Thou shalt be no priest to me ..." It is a mistake to understand this as reference merely to the priesthood which was pagan.  It is the nation which is addressed here: "My people ... thou ... thou shalt be no priest to me."  The spirit and intention of  Exodus 19:6 dominate this verse. It is the nation of Israel as a nation of priests unto God.
