Theophylact of Ohrid
Catena Aurea · Lukasevangelium 17
Lk 17, Verses 3–4English original
Take heed to yourselves: If thy brother trespass against thee, rebuke him; and if he repent, forgive him. And if he trespass against thee seven times in a day, and seven times in a day turn again to thee, saying, I repent; thou shalt forgive him.
But some one may well ask, If when I have several times forgiven my brother he again trespass against me, what must I do with him? In answer therefore to this question He adds, And if he trespass against thee seven times in a day, and seven times in a day turn again to thee, saying, I repent; forgive him.
