Mark 9:41-45

For whoever gives you a cup of water to drink because of your name as followers of Christ, truly I say to you, he shall by no means lose his reward.

“Whoever causes one of these little ones who believe in Me to sin, it is better for him if a heavy millstone is hung around his neck and he is thrown into the sea.

And if your hand causes you to sin, cut it off; it is better for you to enter life maimed, than, having your two hands, to go into hell, into the unquenchable fire.

And if your foot is causing you to sin, cut it off; it is better for you to enter life without a foot, than, having your two feet, to be thrown into hell.
