Numbers 4:17

וְכִלָּה אַֽהֲרֹן־וּבָנָיו לְכַסֹּת אֶת־הַקֹּדֶשׁ וְאֶת־כָּל־כְּלֵי הַקֹּדֶשׁ בִּנְסֹעַ הַֽמַּחֲנֶה וְאַחֲרֵי־כֵן יָבֹאוּ בְנֵי־קְהָת לָשֵׂאת וְלֹֽא־יִגְּעוּ אֶל־הַקֹּדֶשׁ וָמֵתוּ אֵלֶּה מַשָּׂא בְנֵֽי־קְהָת בְּאֹהֶל מוֹעֵֽד

And when Aaron and his sons have made an end of covering the holy furniture, and all the holy vessels, as the camp is to set forward—after that, the sons of Kohath shall come to bear them; but they shall not touch the holy things, lest they die. These things are the burden of the sons of Kohath in the tent of meeting.

וּפְקֻדַּת אֶלְעָזָר בֶּן־אַהֲרֹן הַכֹּהֵן שֶׁמֶן הַמָּאוֹר וּקְטֹרֶת הַסַּמִּים וּמִנְחַת הַתָּמִיד וְשֶׁמֶן הַמִּשְׁחָה פְּקֻדַּת כָּל־הַמִּשְׁכָּן וְכָל־אֲשֶׁר־בּוֹ בְּקֹדֶשׁ וּבְכֵלָֽיו

And the charge of Eleazar the son of Aaron the priest shall be the oil for the light, and the sweet incense, and the continual meal-offering, and the anointing oil: he shall have the charge of all the tabernacle, and of all that therein is, whether it be the sanctuary, or the furniture thereof.’

אַל־תַּכְרִיתוּ אֶת־שֵׁבֶט מִשְׁפְּחֹת הַקְּהָתִי מִתּוֹךְ הַלְוִיִּֽם

’Cut ye not off the tribe of the families of the Kohathites from among the Levites;

וְזֹאת עֲשׂוּ לָהֶם וְחָיוּ וְלֹא יָמֻתוּ בְּגִשְׁתָּם אֶת־קֹדֶשׁ הַקֳּדָשִׁים אַהֲרֹן וּבָנָיו יָבֹאוּ וְשָׂמוּ אוֹתָם אִישׁ אִישׁ עַל־עֲבֹדָתוֹ וְאֶל־מַשָּׂאֽוֹ

but thus do unto them, that they may live, and not die, when they approach unto the most holy things: Aaron and his sons shall go in, and appoint them every one to his service and to his burden;
