Malachi 4:1  KJV  "For, behold, the day cometh, that shall burn as an oven;  and all the proud, yea, and all that do wickedly, shall be stubble:  and the day that cometh shall burn them up, saith the Lord of hosts, that it shall leave them neither root nor branch."

Interpretation based on the following study:  To fully possess and occupy always, to instruct and diligently teach daily;  to continuously cohabit, and permanently establish us, in full knowledge, to enable us to cheerfully announce the good news, that God accomplished all to make us shine.  All and any pride and every insolent and presumptuous thing, and all that practice with an inward commitment to live life apart separate from God, forsaking His law to depart from Him, shall become dry and sapless in waste and ruin; to be enwrapped in secrecy and rankle in covert enchantment.  The longing and sorrow of God to bring them unto Himself to speak His heart and will daily, to appoint and teach each one, so that none need be given up or relinquished to destitution;  to be abundantly and firmly rooted in Him as He covers us and delivers to save us, to encompass to liberally supply and furnish with His deliverance and protection.
