Exodus 39:1

ומן התכלת והארגמן וגו׳ AND OF THE BLUE PURPLE AND OF THE RED PURPLE etc. — But there is no mention of linen here. From this fact I derive (cf. Rashi on Exodus 31:10) that these בגדי שרד mentioned here were not identical with the garments of the priests, for there was linen in the garments of the priests. But these were the cloths with which they covered up the holy vessels at the time of removing and packing up the articles in the Tabernacle when they set out on their journeyings which indeed had no linen in them.

And of the blue, and purple, and scarlet, they made uniforms, with which to do service in the holy place, and they made the holy garments for Aharon; as the Lord commanded Moshe.

וּמִן־הַתְּכֵ֤לֶת וְהָֽאַרְגָּמָן֙ וְתוֹלַ֣עַת הַשָּׁנִ֔י עָשׂ֥וּ בִגְדֵי־שְׂרָ֖ד לְשָׁרֵ֣ת בַּקֹּ֑דֶשׁ וַֽיַּעֲשׂ֞וּ אֶת־בִּגְדֵ֤י הַקֹּ֙דֶשׁ֙ אֲשֶׁ֣ר לְאַהֲרֹ֔ן כַּאֲשֶׁ֛ר צִוָּ֥ה יְהֹוָ֖ה אֶת־מֹשֶֽׁה׃ {פ}
