Four distinct verses are cited to teach that a kohen who performs a service in the Temple without wearing the prescribed priestly garments renders the sacrifice invalid. Each verse contributes a unique aspect to this halakha, clarifying different scenarios. A braita further analyzes various garment-related issues—such as garments that are too long or too short, worn out, duplicated (e.g., wearing two pairs of pants), or missing one garment. It distinguishes between cases that invalidate the service and those that do not. However, statements by Shmuel and Rav regarding overly long or short garments appear to contradict the braita, which does not disqualify those cases. These apparent contradictions are addressed and resolved through deeper analysis. Additionally, several drashot are derived from the Torah's use of the word "bad" in describing the kohen's clothing. The term is interpreted to mean fine linen, and the derivation of this meaning is explored through textual and linguistic analysis.
