Matthew 18:21-23King James Version (KJV)
21 Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times?
22 Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven.
23 Therefore is the kingdom of heaven likened unto a certain king, which would take account of his servants.
