“Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven.”
Matthew 18:22 — Greek Interlinear
Church Fathers on Matthew 18:22
The Lord had said above, 'See that ye despise not one of these little ones,' and had added, 'If thy brother sin against thee, &c.' making also a promise, 'If two of you, &c.' by which the Apostle Peter was led to ask, 'Lord, how oft shall my brother sin against me, and I forgive him?' And to his question he adds an opinion, 'Until seven times?'
Peter thought that he had made a large allowance; but what answers Christ the Lover of men? it follows, 'Jesus saith unto him, I say not unto thee, Until seven times, but, Until seventy times seven.'
I am bold to say, that if he shall sin seventy-eight times, thou shouldest forgive him; yea, and if a hundred; and how oft soever he sin against thee, forgive him. For if Christ found a thousand sins, yet forgave them all, do not you withdraw your forgiveness. For the Apostle says, 'Forgive one another, if any man hath a quarrel against any, even as God in Christ forgave you.' [Col 3:13]
