바미드바르 (민수기) 8:19

ואתנה וגו׳ AND I HAVE GIVEN [THE LEVITES etc.] — Five times are the “children of Israel” mentioned in this verse (where the last four times they might have been alluded to by a personal pronoun), in order to show what affection they are held by the Lord in that the mention of them is repeated five times in one verse corresponding in number to the “Five Books of the Torah”. Thus I have seen stated in Genesis Rabbah (Leviticus Rabbah 2:4; cf. Genesis Rabbah 3:5). ולא יהיה בבני ישראל נגף [AND I HAVE GIVEN THE LEVITES … TO DO THE SERVICE OF THE CHILDREN OF ISRAEL] THAT THERE BE NO PLAGUE AMONG THE CHILDREN OF ISRAEL [WHEN THE CHILDREN OF ISRAEL COME NIGH UNTO THE SANCTUARY] — The meaning is: I have given them etc. so that it should be unnecessary for them to come near to the Sanctuary, because [having sinned by worshipping the Calf], if they came near there would be a plague among them.

וָאֶתְּנָ֨ה אֶת־הַלְוִיִּ֜ם נְתֻנִ֣ים ׀ לְאַהֲרֹ֣ן וּלְבָנָ֗יו מִתּוֹךְ֮ בְּנֵ֣י יִשְׂרָאֵל֒ לַעֲבֹ֞ד אֶת־עֲבֹדַ֤ת בְּנֵֽי־יִשְׂרָאֵל֙ בְּאֹ֣הֶל מוֹעֵ֔ד וּלְכַפֵּ֖ר עַל־בְּנֵ֣י יִשְׂרָאֵ֑ל וְלֹ֨א יִהְיֶ֜ה בִּבְנֵ֤י יִשְׂרָאֵל֙ נֶ֔גֶף בְּגֶ֥שֶׁת בְּנֵֽי־יִשְׂרָאֵ֖ל אֶל־הַקֹּֽדֶשׁ׃

And I have given the Levites as a gift to Aharon and to his sons from among the children of Yisra᾽el, to do the service of the children of Yisra᾽el in the Tent of Meeting, and to make atonement for the children of Yisra᾽el: that there be no plague among the children of Yisra᾽el, when the children of Yisra᾽el come near to the sanctuary.
