The angel of the LORD encampeth round about them that fear him, and delivereth them.- Psalms 34:7

Psalms 27:1 The LORD is my light and my salvation;  whom shall I fear?  the LORD is the strength of my life;  of whom shall I be afraid?  2 When the wicked, even mine enemies and my foes, came upon me to eat up my flesh, they stumbled and fell.   3 Though an host should encamp against me, my heart shall not fear:  though war should rise against me, in this will I be confident. 

Isaiah 59:11 When the enemy shall come in like a flood, the Spirit of the LORD shall lift up a standard against him.  

Isaiah 54:17 No weapon that is formed against thee shall prosper;  and every tongue that shall rise against thee in judgment thou shalt condemn.   This is the heritage of the servants of the LORD, and their righteousness is of me, saith the LORD.  

For thou hast been a shelter for me, and a strong tower from the enemy.- Psalms 61:3

Because he hath set his love upon me, therefore will I deliver him: I will set him on high, because he hath known my name. He shall call upon me, and I will answer him: I will be with him in trouble; I will deliver him, and honour him.- Psalms 91:14-15

And Jesus rebuked the devil; and he departed out of him: and the child was cured from that very hour. Then came the disciples to Jesus apart, and said, Why could not we cast him out? And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you. Howbeit this kind goeth not out but by prayer and fasting.- Matthew 17:18-21

And Jesus returned in the power of the Spirit into Galilee: and there went out a fame of him through all the region round about. And he taught in their synagogues, being glorified of all. And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read. And there was delivered unto him the book of the prophet Esaias. And when he had opened the book, he found the place where it was written, The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised,- Luke 4:14-18

Submit yourselves therefore to God. Resist the devil, and he will flee from you.- James 4:7

And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night. And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.- Revelation 12:10-11
