Luke 17:1-6

1 And he said unto the disciples, `It is impossible for the stumbling blocks not to come, but wo [to him] through whom they come;

2 it is more profitable to him if a weighty millstone is put round about his neck, and he hath been cast into the sea, than that he may cause one of these little ones to stumble.

3 `Take heed to yourselves, and, if thy brother may sin in regard to thee, rebuke him, and if he may reform, forgive him,

4 and if seven times in the day he may sin against thee, and seven times in the day may turn back to thee, saying, I reform; thou shalt forgive him.'

5 And the apostles said to the Lord, `Add to us faith;'

6 and the Lord said, `If ye had faith as a grain of mustard, ye would have said to this sycamine, Be uprooted, and be planted in the sea, and it would have obeyed you.
