Even from the days of your fathers ye are gone away from mine ordinances, and have not kept them. Return unto me, and I will return unto you, saith the LORD of hosts. But ye said, Wherein shall we return? Gone away from mine ordinances - Never acting according to their spirit and design.
Return unto me - There is still space to repent.
Wherein shall we return? - Their consciences were seared, and they knew not that they were sinners.
