Matthew 18:21

19Again 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.

20For where two or three are gathered together in my name, there am I in the midst of them.

21Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times?

22Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven.

23Therefore is the kingdom of heaven likened unto a certain king, which would take account of his servants.
