וְהַחֹנִ֣ים לִפְנֵ֣י הַמִּשְׁכָּ֡ן קֵ֣דְמָה לִפְנֵי֩ אֹֽהֶל־מוֹעֵ֨ד ׀ מִזְרָ֜חָה מֹשֶׁ֣ה ׀ וְאַהֲרֹ֣ן וּבָנָ֗יו שֹֽׁמְרִים֙ מִשְׁמֶ֣רֶת הַמִּקְדָּ֔שׁ לְמִשְׁמֶ֖רֶת בְּנֵ֣י יִשְׂרָאֵ֑ל וְהַזָּ֥ר הַקָּרֵ֖ב יוּמָֽת׃
Yang berkemah di depan Kemah Suci di sebelah timur, di depan Kemah Pertemuan ke arah matahari terbit, ialah Musa, serta Harun dan anak-anaknya. Mereka menjalankan tugas menjaga tempat kudus, sebagai tugas bagi orang Israel. Orang awam yang mendekat akan dihukum mati.
Rashi
משה ואהרן ובניו [BUT THOSE THAT ENCAMP BEFORE THE DWELLING … SHALL BE] MOSES, AND AARON AND HIS SONS — and adjacent to him was the standard of the camp of Judah, and next to the latter were encamped Issachar and Zebulun — “Well is it with the righteous, well with his neighbour!” Because they (the sons of Judah, Issachar and Zebulun) were the neighbours of Moses who occupied himself with the Torah, they themselves became eminent scholars in the Law, as it is said, (Psalms 60:9) “Judah is my lawgiver”; (I Chronicles 12:32) “and of the children of Issachar which were men that had understanding of the times to know what Israel had to do [the heads of them were two hundred]” — i.e., two hundred heads of the Sanhedrin; and (Judges 5:14) “and out of Zebulun came those that handle the pen of the writer” (Midrash Tanchuma, Bamidbar 12).
Kitzur Ba'al HaTurim
Moshe and Aharon. There is a pause between Moshe and Aharon, to inform that Moshe was alone in one place, and Aharon and his sons were alone in another place.
Siftei Chakhamim
Near them. (Gur Aryeh) Here too, Rashi comes to answer the question: It should have stated “Moshe, Aharon and his sons shall camp in front of the Tent of Meeting.” However the Torah is not coming to instruct them, only to inform that those who camped in front of the Tent of Meeting were these important individuals, therefore those people who camped near them were like them.
