Matthew 18:6-9

“Whoever causes one of these little ones who believe in me to sin, it would be better for him to have a great millstone hung around his neck and to be drowned in the depths of the sea. Woe to the world because of things that cause sin! Such things must come, but woe to the one through whom they come! If your hand or foot causes you to sin, cut it off and throw it away. It is better for you to enter into life maimed or crippled than with two hands or two feet to be thrown into eternal fire. And if your eye causes you to sin, tear it out and throw it away. It is better for you to enter into life with one eye than with two eyes to be thrown into fiery Gehenna. The Parable of the Lost Sheep.
