Priestly robe (Judaism)

The lower hem of the garment was fringed with small golden bells alternating with pomegranate-shaped tassels of blue (turquoise), purple and scarlet wool (Exodus 28:33–34).

[4] Rashi points out in his commentary on the Talmud that the fashioning and wearing of the priestly robe atoned for the sin of lashon hara on the part of the Israelites in Zevachim 88b.

As the High Priest walked, the bells noisily announced his presence, and because the noise emanated from the robe, it served as a reminder for people to refrain from gossip.

[citation needed] The Talmud also states that the tassels between each bell on the robe were made of turquoise, purple, and scarlet wool.

These three materials signify the three people injured when Lashon Hara is spoken: the speaker, the listener, and the one who is talked about.
