This week we will detail which disqualifications (pesulei avodah – disqualifications of the sacrificial service) invalidate the Temple service—such as a zar (non-kohen), tamei (ritually impure), onen (a mourner on the day of burial), tevul-yom (one who immersed in a mikveh that day but must wait until nightfall), mechusar begadim (lacking the proper priestly garments), or sh’tuyei yayin (a kohen who drank wine)—deriving each from verses and showing how they apply in the Mikdash but not on a bamah (private altar). The Gemara further clarifies laws of priestly garments (too few, extra, torn, or soiled), belt placement, and chatzitzah (a barrier between the garments and the body), and then transitions to the requirement of kidush yadayim v’raglayim (sanctifying the hands and feet with water), including whether it lapses overnight and the mechanics of the kiyor (laver).
