Reference for Moed Katan 9:20

רב חיננא אמר הרימו מכשול מדרך עמי ר' יהושע בריה דרב אידי אמר (שמות יח, כ) והודעת להם את הדרך (אשר) ילכו בה

It is require for what has been taught: And he shall cry 'Unclean! Unclean!'; [this teaches that] one must needs make his distress known to many, that many pray for mercy on his behalf? - If that be so, let the text read 'Unclean' [but once]; why has it 'Unclean', 'Unclean' [twice over]? Infer [from it] the two points.
