וְאַתָּ֡ה הַפְקֵ֣ד אֶת־הַלְוִיִּם֩ עַל־מִשְׁכַּ֨ן הָעֵדֻ֜ת וְעַ֣ל כָּל־כֵּלָיו֮ וְעַ֣ל כָּל־אֲשֶׁר־לוֹ֒ הֵ֜מָּה יִשְׂא֤וּ אֶת־הַמִּשְׁכָּן֙ וְאֶת־כָּל־כֵּלָ֔יו וְהֵ֖ם יְשָׁרְתֻ֑הוּ וְסָבִ֥יב לַמִּשְׁכָּ֖ן יַחֲנֽוּ׃
mas tu põe os levitas sobre o tabernáculo do testemunho, sobre todos os seus móveis, e sobre tudo o que lhe pertence. Eles levarão o tabernáculo e todos os seus móveis, e o administrarão; e acampar-se-ão ao redor do tabernáculo.
Rashi on Numbers
ואתה הפקד את הלוים BUT THOU SHALT APPOINT THE LEVITES OVERSEERS [OVER THE TABERNACLE etc.] — Understand the word הפקד as the Targum does: ,מני “appoint”; it (the word מני) is an expression for appointing a person to control that thing over which he has been appointed; similar is, (Esther 2:3) “and let the king appoint (ויפקד) officers”.
Sforno on Numbers
ואתה הפקד, the commandment to count them is repeated to make clear that they are in a class by themselves. The reason was that only this census rated as a holy activity.
