I'm pretty sure the Bible, in fact, does NOT say that, but I get your meaning.
Here are the EXACT Biblical quotes on that topic.
Matthew 18:6

Mark 9:42
“And if anyone causes one of these little ones who believe in me to sin, it would be better for him to be thrown into the sea with a large millstone tied around his neck.
Luke 17:2
It would be better for him to be thrown into the sea with a millstone tied around his neck than for him to cause one of these little ones to sin.
Luke 17:2
