וַיָּ֥שֶׂם אֶת־הַמִּצְנֶ֖פֶת עַל־רֹאשׁ֑וֹ וַיָּ֨שֶׂם עַֽל־הַמִּצְנֶ֜פֶת אֶל־מ֣וּל פָּנָ֗יו אֵ֣ת צִ֤יץ הַזָּהָב֙ נֵ֣זֶר הַקֹּ֔דֶשׁ כַּאֲשֶׁ֛ר צִוָּ֥ה יְהוָ֖ה אֶת־מֹשֶֽׁה׃
Lalu ia mengenakan serban di kepalanya, dan pada serban itu, tepat di depan wajahnya, ia memasang lempengan emas, mahkota kudus, seperti yang diperintahkan Yang Mahakekal kepada Musa.
Rashi
