Whether one cooked in it or poured hot [liquid] into it, whether [it was the meat of] the most holy offerings or [of] the offerings of lesser holiness — they require purging and rinsing. R’ Shimon says: Offerings of lesser holiness do not require purging and rinsing. R’ Tarfon says: If one cooked in it from the beginning of the festival, he may [continue to] cook in it for the entire festival. But the Sages say: With the conclusion of the period of eating [comes the requirement of] purging and rinsing. Purging [is] as one purges a cup, and rinsing [is] as one rinses a cup; purging (is done with hot water) and rinsing is with cold water. The spit and the grill are purged in hot water.
