Ye shall not fear them: for the Lord your God he shall fight for you. Deuteronomy 3:22 KJV
There is absolutely no reason to fear anything or anyone when you are in covenant with Almighty God. He will watch over you and give His angels charge to protect you.
When surrounded by an enemy army, the prophet was protected by a great angelic host that over came them and put the man of God in complete control of the situation.
And he answered, Fear not: for they that be with us are more than they that be with them. 2 Kings 6:16 KJV
Remember, God is Love and perfect Love casts out all fear.
And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him. 1 John 4:16 KJV
There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love.
1 John 4:18 KJV
