Targum for Numbers 4:12

וְלָקְחוּ֩ אֶת־כָּל־כְּלֵ֨י הַשָּׁרֵ֜ת אֲשֶׁ֧ר יְשָֽׁרְתוּ־בָ֣ם בַּקֹּ֗דֶשׁ וְנָֽתְנוּ֙ אֶל־בֶּ֣גֶד תְּכֵ֔לֶת וְכִסּ֣וּ אוֹתָ֔ם בְּמִכְסֵ֖ה ע֣וֹר תָּ֑חַשׁ וְנָתְנ֖וּ עַל־הַמּֽוֹט׃

And they shall take all the vessels of ministry, wherewith they minister in the sanctuary, and put them in a cloth of blue, and cover them with a covering of sealskin, and shall put them on a bar.
