וָאֹמַ֕ר יָשִׂ֛ימוּ צָנִ֥יף טָה֖וֹר עַל־רֹאשׁ֑וֹ וַיָּשִׂימוּ֩ הַצָּנִ֨יף הַטָּה֜וֹר עַל־רֹאשׁ֗וֹ וַיַּלְבִּשֻׁ֙הוּ֙ בְּגָדִ֔ים וּמַלְאַ֥ךְ יְהוָ֖ה עֹמֵֽד׃
And I said: ‘Let them set a fair mitre upon his head.’ So they set a fair mitre upon his head, and clothed him with garments; and the angel of the LORD stood by.
Rashi on Zechariah
“Let them put a pure miter, etc.” I begged mercy for him.
