Matthew 18:6-7

Young's Literal Translation

⁶ and whoever may cause to stumble one of those little ones who are believing in me, it is better for him that a weighty millstone may be hanged upon his neck, and he may be sunk in the depth of the sea.

⁷ `Wo to the world from the stumbling-blocks! for there is a necessity for the stumbling-blocks to come, but wo to that man through whom the stumbling-block doth come!
