(יד) וְהִבְדַּלְתָּ֙ אֶת־הַלְוִיִּ֔ם מִתּ֖וֹךְ בְּנֵ֣י יִשְׂרָאֵ֑ל וְהָ֥יוּ לִ֖י הַלְוִיִּֽם׃ (טו) וְאַֽחֲרֵי־כֵן֙ יָבֹ֣אוּ הַלְוִיִּ֔ם לַעֲבֹ֖ד אֶת־אֹ֣הֶל מוֹעֵ֑ד וְטִֽהַרְתָּ֣ אֹתָ֔ם וְהֵנַפְתָּ֥ אֹתָ֖ם תְּנוּפָֽה׃
(14) Thus you shall set the Levites apart from the Israelites, and the Levites shall be Mine. (15) Thereafter the Levites shall be qualified for the service of the Tent of Meeting, once you have cleansed them and designated them as an elevation offering.
(כד) זֹ֖את אֲשֶׁ֣ר לַלְוִיִּ֑ם מִבֶּן֩ חָמֵ֨שׁ וְעֶשְׂרִ֤ים שָׁנָה֙ וָמַ֔עְלָה יָבוֹא֙ לִצְבֹ֣א צָבָ֔א בַּעֲבֹדַ֖ת אֹ֥הֶל מוֹעֵֽד׃ (כה) וּמִבֶּן֙ חֲמִשִּׁ֣ים שָׁנָ֔ה יָשׁ֖וּב מִצְּבָ֣א הָעֲבֹדָ֑ה וְלֹ֥א יַעֲבֹ֖ד עֽוֹד׃
(24) This is the rule for the Levites. From twenty-five years of age up they shall participate in the work force in the service of the Tent of Meeting; (25) but at the age of fifty they shall retire from the work force and shall serve no more.
1) Why was it necessary to assign this role to one of the tribes?
2) Are there any similarities in your chosen field of work as professional Jewish educators to the role of work as professional Jewish educators to the role oftheLevites?
3) Why do you suppose the Levites were "mustered out" at age 50?
