And blessed is he, to whom I shall not be a stumbling block.

And he said to his disciples, It is impossible for the stumbling-blocks not to come, but woe to him through whom they come!

But Jesus looked at them and said, "Then what does it mean that is written [Psa. 118:22], 'The building block rejected by the builders [is] the same [one] that was made the principal stone by which the entire building was aligned?'

Whosoever stumble at that stone, shall be broken: but on whosoever it fall upon, it will grind him to powder."

It would be better for him that a millstone were hanged about his neck, and he was cast into the sea, than that he should cause one of these little ones to stumble.

He also told them a parable: “Can a blind man guide [another] blind man? Will they not both fall into a hole in the ground?
