Matthew 18:6

4 Therefore, whoever humbles himself like this little child is the greatest in the kingdom of heaven.

5 And whoever welcomes a little child like this in My name welcomes Me.

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 drowned in the depths of the sea.

7 Woe to the world for the causes of sin. These stumbling blocks must come, but woe to the man through whom they come!

8 If your hand or your foot causes you to sin, cut it off and throw it away. It is better for you to enter life crippled or lame than to have two hands and two feet and be thrown into the eternal fire.

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