(1) The same law applies to filling-in the cracks in the walls of the pit with plaster ("Shafin"), an act which all of the Beraisos cited in the Gemara compare to Chatitah. (The Girsa of the last Beraisa which says, "We may do Chatitah but not fill-in the cracks in the walls," is incorrect, as the DIKDUKEI SOFRIM points out, and as is evident from the RIF, ROSH, and other Rishonim who all omit the part of that Beraisa that mentions not filling-in the cracks. See also RASHASH.)

(2) The Rishonim give three different interpretations for "Tzerichim Lo" (its water is needed) and "Einam Tzerichim Lo" (its water is not needed), as cited by the RITVA:

a. "Tzerichim Lo" -- it is needed for drinking; "Einam Tzerichim Lo" -- it is not needed for drinking but for other purposes (RASHI).

b. "Tzerichim Lo" -- it is needed immediately after the festival; "Einam Tzerichim Lo" -- it is not needed until long after the festival has passed (TOSFOS).

c. "Tzerichim Lo" -- it is needed for drinking, and the only other water available is far away; "Einam Tzerichim Lo" -- there is another supply of water nearby, but the individual person (or group) prefers to use his own water supply (RAMBAN).

(3) The Beraisa cited by the Gemara adds that even though "Chotetin Osan" is permitted, "Chotetin l'Sochan" is not permitted. See Insights for explanations of these terms.
