Luke 17:3

1Then said he unto the disciples, It is impossible but that offences will come: but woe unto him, through whom they come!

2It were better for him that a millstone were hanged about his neck, and he cast into the sea, than that he should offend one of these little ones.

3Take heed to yourselves: If thy brother trespass against thee, rebuke him; and if he repent, forgive him.

4And 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.

5And the apostles said unto the Lord, Increase our faith.
