Numbers 3:6

וַיָּמָת נָדָב וַאֲבִיהוּא לִפְנֵי יְהוָה בְּֽהַקְרִבָם אֵשׁ זָרָה לִפְנֵי יְהוָה בְּמִדְבַּר סִינַי וּבָנִים לֹא־הָיוּ לָהֶם וַיְכַהֵן אֶלְעָזָר וְאִיתָמָר עַל־פְּנֵי אַהֲרֹן אֲבִיהֶֽם

And Nadab and Abihu died before the LORD, when they offered strange fire before the LORD, in the wilderness of Sinai, and they had no children; and Eleazar and Ithamar ministered in the priest’s office in the presence of Aaron their father.

וַיְדַבֵּר יְהוָה אֶל־מֹשֶׁה לֵּאמֹֽר

And the LORD spoke unto Moses, saying:

וְשָׁמְרוּ אֶת־מִשְׁמַרְתּוֹ וְאֶת־מִשְׁמֶרֶת כָּל־הָעֵדָה לִפְנֵי אֹהֶל מוֹעֵד לַעֲבֹד אֶת־עֲבֹדַת הַמִּשְׁכָּֽן

And they shall keep his charge, and the charge of the whole congregation before the tent of meeting, to do the service of the tabernacle.

וְשָׁמְרוּ אֶֽת־כָּל־כְּלֵי אֹהֶל מוֹעֵד וְאֶת־מִשְׁמֶרֶת בְּנֵי יִשְׂרָאֵל לַעֲבֹד אֶת־עֲבֹדַת הַמִּשְׁכָּֽן

And they shall keep all the furniture of the tent of meeting, and the charge of the children of Israel, to do the service of the tabernacle.
