Mattityahu 18:5-7

Orthodox Jewish Bible

⁵ And whoever receives one such yeled in my Name receives me [Moshiach].

⁶ But whoever causes a michshol (stumbling block) for one of these little ones, who have emunah in me, it is better for him that a heavy millstone be hung around his neck, and that he be drowned in the depth of the sea.

⁷ Oy lOlam (Woe to the World) because of its michsholim (stumbling blocks)! For it is inevitable that michsholim come; but oy to that man through whom the michshol comes.
