Luke 22 v 3 Then entered Satan into Judas, surnamed Iscariot, being one of the twelve. 2 Corinthians 11 v 14 And no marvel, for Satan himself is transformed into an angel of light. 

Paul wrote : And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure. 

2 Corinthians 12 v 7
Therefore we would have come unto you—even I, Paul, time and again—but Satan hindered us. 1 Thess 2 v 18 even him, whose coming is according to the working of Satan, with all power and signs and lying wonders, 2 Thess 2 v 9 

1 Timothy 1 v 20 Among them are Hymenaeus and Alexander, whom I have delivered unto Satan, that they may learn not to blaspheme. 1 Chronicles 21 v 1 And Satan stood up against Israel, and provoked David to number Israel. 

Now there was a day when the sons of God came to present themselves before the LORD, and Satan also came among them. Job 1 v 6 Zec 3 v 1 And he showed me Joshua the high priest standing before the angel of the LORD, and Satan standing at his right hand to resist him. And the LORD said unto Satan, “The LORD rebuke thee, O Satan; even the LORD who hath chosen Jerusalem rebuke thee! Is not this a brand plucked out of the fire?” 

Revelation 12:9 And the great dragon was cast out—that serpent of old called the Devil and Satan, who deceived the whole world 

Rev 20 v 2 And he laid hold on the dragon, that old serpent, who is the devil and Satan, and bound him for a thousand years. 

Rev 20 v 7 And when the thousand years are expired, Satan shall be loosed out of his prison, “How art thou fallen from heaven, O Lucifer, son of the morning! How art thou cut down to the ground, who didst weaken the nations! Isaiah 14 v 12 – 16  They that see thee shall narrowly look upon thee and consider thee, saying, ‘Is this the man that made the earth to tremble, that did shake kingdoms, Matthew 4 v 10 Then said Jesus unto him, “Get thee hence, Satan! For it is written: ‘Thou shalt worship the Lord thy God, and Him only shalt thou serve.’” 

Matthew 12 v 26 And if Satan cast out Satan, he is divided against himself; how then shall his kingdom stand? Matthew 16 v 23 But He turned and said unto Peter, “Get thee behind Me, Satan! Thou art an offense unto Me; for thou savourest not the things that be of God, but those that be of men.” 

Greater is He that is within me.
1 John 4 v 4 Ye are of God, little children, and have overcome them, because greater is He that is in you than he that is in the world.
