Luke 17:4

2 It 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.

3 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.

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

6 And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you.

Do read the surrounding verses too, because the context often says more than a single verse.
