Mattityahu 18:1-14

At that time, the talmidim approached Rebbe, Melech HaMoshiach with this she'elah saying, Who then is greatest in the Malchut HaShomayim? And having called a yeled to himself, he set him before them, and said, Omein, I say to you, unless you change inwardly and have a complete turn around and become like yeladim, you shall never enter the Malchut HaShomayim. Therefore, whoever humbles himself as this yeled, he is the greatest in the Malchut HaShomayim. And whoever receives one such yeled in my Name receives me. 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. 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. And if your hand or your foot causes a michshol for you, cut it off, and throw it from you. It is better for you to enter Chayyim crippled or as one of the pisechim (lame), than, having two hands and two feet, to be cast into the Eish Olam (Eternal Fire). And if your eye causes a michshol for you, pluck it out and throw it from you. It is better for you to enter Chayyim one-eyed than, having two eyes, to be cast into the Gehinnom HaEish. See to it that you do not look down on one of these little ones, for I say to you that their malachim which are in Shomayim continually behold the face of Avi shbaShomayim (my Father who is in Heaven). For the Bar Enosh came to save that which was lost. What do you think? If any man owns a hundred kevesim (sheep) and one of them has gone astray, does he not leave the ninety-nine on the hillsides and go and search for the one that is straying? And if it turns out that he finds it, beemes I say to you, he has more simcha (joy) over it than over the ninety-nine which have not gone astray. Thus it is not the ratzon HASHEM, the will of your Av shbaShomayim, that one of these little ones perish.
