Matthew 18:9

6 but whoever causes one of these little ones who believe in me to stumble, it would be better for him if a huge millstone were hung around his neck and that he were sunk in the depths of the sea.

7 “Woe to the world because of occasions of stumbling! For it must be that the occasions come, but woe to that person through whom the occasion comes!

8 If your hand or your foot causes you to stumble, cut it off and cast it from you. It is better for you to enter into life maimed or crippled, rather than having two hands or two feet to be cast into the eternal fire.

9 If your eye causes you to stumble, pluck it out and cast it from you. It is better for you to enter into life with one eye, rather than having two eyes to be cast into the Gehenna of fire.

10 See that you don’t despise one of these little ones, for I tell you that in heaven their angels always see the face of my Father who is in heaven.

11 For the Son of Man came to save that which was lost.

12 “What do you think? If a man has one hundred sheep, and one of them goes astray, doesn’t he leave the ninety-nine, go to the mountains, and seek that which has gone astray?
