Matthew 18:6

“However, so that we do not offend them, go to the sea and throw in a hook, and take the first fish that comes up; and when you open its mouth, you will find a stater. Take that and give it to them for Me and you.”

“And 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.

“It would be better for him if a millstone were hung around his neck and he were thrown into the sea, than that he would cause one of these little ones to stumble.

And in that way, by sinning against the brothers and wounding their conscience when it is weak, you sin against Christ.
