Luke 22:3  KJV  "Then entered Satan into Judas surnamed Iscariot, being of the number of the twelve."

Interpretation based on the following study:  Appearing to occupy a space in the midst of the people, rising up antagonistically and seditiously against the Son.  The accuser satan, working to enslave, oppress, envelop and bind in darkness.  Passing over God's Law, Order and Covenant as if not binding, causing alienation and separation by calling into question God's Way and Truth.  Lawless to extort and defraud, throwing the assembly into disorder and confusion, maligning to delude, with the intent to end the celebration and worship of God.  Holding out by force to charge the Son, appealing to summon with ulterior motives, contrary and hostile to slander and depilate.  Conspiring in treason and confederacy, assembling together to tear to pieces in hardhearted denseness.  Becoming sapless, unfeeling and obstinate to wrestle Origin and Completion.  Given wholly to gain by finding fault with the Son, especially for evil, to disgrace and shame with baseness.  Falsely representing and maligning the Son of Heaven and His Divine Administration.
