Deuteronomy 32:30 King James Version (KJV)
30 How should one chase a thousand, and two put ten thousand to flight, except their Rock had sold them, and the Lord had shut them up?
Matthew 18:18-20 King James Version (KJV)
18 Verily I say unto you, Whatsoever ye shall bind on earth shall be bound in heaven: and whatsoever ye shall loose on earth shall be loosed in heaven.
19 Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven.
20 For where two or three are gathered together in my name, there am I in the midst of them.
