Zevachim 19A

כנגד אצילי ידיהן.

at the level of their elbows.

אמר רב אשי, אמר לי הונא בר נתן: זימנא חדא הוה קאימנא קמיה דאיזגדר מלכא והוה מדלי לי המיינאי, ותיתייה ניהליה, ואמר לי: ״ממלכת כהנים וגוי קדוש״ כתיב בכו. כי אתאי קמיה דאמימר, אמר לי: אקיים בך ״והיו מלכים אמניך״.

Rav Ashi says: Huna bar Natan said to me: Once, I was standing before Izgadar, king of Persia, and my belt was raised above its appropriate height, and he lowered it into place and said to me: “A kingdom of priests, and a holy nation” (Exodus 19:6), is written about you; therefore, you should always look dignified. When I came before Ameimar and recounted this incident, he said to me: With regard to you, God’s promise to Israel: “And kings should be your foster fathers” (Isaiah 49:23), was fulfilled.

תנן התם: כהן שלקה באצבעו ⁠– כורך עליה גמי במקדש, אבל לא במדינה. ואם להוציא ממנה דם ⁠– כאן וכאן אסור.

§ With regard to the priestly vestments, we learned in a Mishnah elsewhere (Eiruvin 103b): A priest who was injured on his finger on Shabbat may temporarily wrap it with a reed so that his wound is not visible while he is serving in the Temple. This leniency applies in the Temple, but not in the rest of the country, as the reed also heals the wound, and medical treatment is prohibited on Shabbat by rabbinic decree. But if his intention is to draw blood from the wound, it is prohibited both here and there.

אמר רבי יהודה בריה דרבי חייא: לא שנו אלא גמי, אבל צילצול קטן ⁠– הוי יתור בגדים. ורבי יוחנן אמר: לא אמרו יתור בגדים אלא במקום בגדים, אבל שלא במקום בגדים ⁠– לא הוי יתור.

R' Yehuda, son of R' Ḥiyya, says: They taught only that a reed is permitted. But a small sash [tziltzul] as a bandage is considered an extra garment and is therefore forbidden, since it is prohibited for a priest to add to the priestly vestments prescribed by the Torah. And R' Yoḥanan says: They said that wearing extra garments is prohibited only if the extra garment is worn in a place on the priest’s body where the requisite vestments are worn. But if the sash is in a place on his body where the vestments are not worn, e.g., on his hand, it is not considered an extra garment.
