ג רבי יוסי אומר הרוצה לטהר מיד מגעילן ברותחין או חולטן במי זיתים רשב"ג אומר משום ר' יוסי מניחן תחת הצינור שמימיו מקלחין או במעיין שמימיו רודפין וכמה עונה כדרך שאמרו ביין נסך כך אמרו בטהרות
3 R. Jose stated: If a person desires to obtain cleanness forthwith he pours over them boiling water or scalds them with olive water. R. Simeon b. Gamaliel citing R. Jose ruled: He puts them under a pipe through which runs a continuous stream of water or in a fountain with flowing water. And for how long? For one 'onah. (As these provisions were applied to yen nesek so were they applied to matters of cleanness. But is not the order<span class="x" onmousemove="('comment',' That compares the laws of cleanness to those of yen nesek v. Glos.

And how long is an 'onah? R. Hiyya b. Abba citing R. Johanan replied: Either a day or a night. R. Hana She'una or, as some say, R. Hana b. She'una citing Rabbah b. Bar Hana who had it from R. Johanan replied: Half a day and half a night. And in connection with this R. Samuel b. R. Isaac explained: There is no real difference between them,<span class="x" onmousemove="('comment',' R.
