Mark 9:41

39 “Do not stop him,” Jesus replied. “For no one who performs a miracle in My name can turn around and speak evil of Me.

40 For whoever is not against us is for us.

Indeed, if anyone gives you even a cup of water because you bear the name of Christ, truly I tell you, he will never lose his reward.

42 But if anyone causes one of these little ones who believe in Me to stumble, it would be better for him to have a large millstone hung around his neck and to be thrown into the sea.

43 If your hand causes you to sin, cut it off. It is better for you to enter life crippled than to have two hands and go into hell, into the unquenchable fire.

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