There’s a line in the Bible somewhere (someone help me out?) about parents who cause their children to sin, and it would be better to have a millstone tied around their (the parents) necks and thrown into the sea.
Matthew 18:6 “but whoever causes one of these little ones who believe in Me to stumble, it would be better for him to have a heavy millstone hung around his neck, and to be drowned in the depth of the sea.”
Mark 9:42 “Whoever causes one of these little ones who believe to stumble, it would be better for him if, with a heavy millstone hung around his neck, he had been cast into the sea.”
