Interpreting the Images on the Flags of the Israelites: Rashi, Ibn Ezra, Midrashim and Milgrom
The text indicates that the banners of the tribes had a military and practical function, as Alter and Milgrom note. Midrashim and medieval commentaries offer homiletical interpretations, explored in this sheet.
(א) וַיְדַבֵּ֨ר יהוה אֶל־מֹשֶׁ֛ה בְּמִדְבַּ֥ר סִינַ֖י בְּאֹ֣הֶל מוֹעֵ֑ד בְּאֶחָד֩ לַחֹ֨דֶשׁ הַשֵּׁנִ֜י בַּשָּׁנָ֣ה הַשֵּׁנִ֗ית לְצֵאתָ֛ם מֵאֶ֥רֶץ מִצְרַ֖יִם לֵאמֹֽר׃ (ב) שְׂא֗וּ אֶת־רֹאשׁ֙ כׇּל־עֲדַ֣ת בְּנֵֽי־יִשְׂרָאֵ֔ל לְמִשְׁפְּחֹתָ֖ם לְבֵ֣ית אֲבֹתָ֑ם בְּמִסְפַּ֣ר שֵׁמ֔וֹת כׇּל־זָכָ֖ר לְגֻלְגְּלֹתָֽם׃
(1) On the first day of the second month, in the second year following the exodus from the land of Egypt, יהוה spoke to Moses in the wilderness of Sinai, in the Tent of Meeting, saying: (2) Take a census of the whole Israelite company [of fighters] by the clans of its ancestral houses, listing the names, every male, head by head.
(ב) אִ֣ישׁ עַל־דִּגְל֤וֹ בְאֹתֹת֙ לְבֵ֣ית אֲבֹתָ֔ם יַחֲנ֖וּ בְּנֵ֣י יִשְׂרָאֵ֑ל מִנֶּ֕גֶד סָבִ֥יב לְאֹֽהֶל־מוֹעֵ֖ד יַחֲנֽוּ׃ (ג) וְהַחֹנִים֙ קֵ֣דְמָה מִזְרָ֔חָה דֶּ֛גֶל מַחֲנֵ֥ה יְהוּדָ֖ה לְצִבְאֹתָ֑ם וְנָשִׂיא֙ לִבְנֵ֣י יְהוּדָ֔ה נַחְשׁ֖וֹן בֶּן־עַמִּינָדָֽב....
(י) דֶּ֣גֶל מַחֲנֵ֧ה רְאוּבֵ֛ן תֵּימָ֖נָה לְצִבְאֹתָ֑ם וְנָשִׂיא֙.... (יח) דֶּ֣גֶל מַחֲנֵ֥ה אֶפְרַ֛יִם לְצִבְאֹתָ֖ם יָ֑מָּה וְנָשִׂיא֙ לִבְנֵ֣י אֶפְרַ֔יִם אֱלִישָׁמָ֖ע בֶּן־עַמִּיהֽוּד׃
(2) The Israelites shall camp each man with his standard, under the banners of their ancestral house; they shall camp around the Tent of Meeting at a distance. (3) Camped on the front, or east side: the standard of the division of Judah, troop by troop. Chieftain of the Judites: Nahshon son of Amminadab.... (10) On the south: the standard of the division of Reuben, troop by troop. Chieftain of the Reubenites: Elizur son of Shedeur As they camp, so they shall march, each in position, by their standards. (18) On the west: the standard of the division of Ephraim, troop by troop. Chieftain of the Ephraimites: Elishama son of Ammihud.
(ב) באחד לחדש השני. לתקן את הדגלים ואיך יסעו ואיך יחנו בעבור המקדש כי בעשרים לחדש השני נסעו:
(2) ON THE FIRST DAY OF THE SECOND MONTH. To tell him to arrange the standards and to instruct him how the Israelites were to journey and how they were to camp with reference to the tabernacle, for they journeyed on the twentieth day of the second month.
(יא) וַיְהִ֞י בַּשָּׁנָ֧ה הַשֵּׁנִ֛ית בַּחֹ֥דֶשׁ הַשֵּׁנִ֖י בְּעֶשְׂרִ֣ים בַּחֹ֑דֶשׁ נַעֲלָה֙ הֶֽעָנָ֔ן מֵעַ֖ל מִשְׁכַּ֥ן הָעֵדֻֽת׃ (יב) וַיִּסְע֧וּ בְנֵֽי־יִשְׂרָאֵ֛ל לְמַסְעֵיהֶ֖ם מִמִּדְבַּ֣ר סִינָ֑י וַיִּשְׁכֹּ֥ן הֶעָנָ֖ן בְּמִדְבַּ֥ר פָּארָֽן.... (יד) וַיִּסַּ֞ע דֶּ֣גֶל מַחֲנֵ֧ה בְנֵֽי־יְהוּדָ֛ה בָּרִאשֹׁנָ֖ה לְצִבְאֹתָ֑ם וְעַ֨ל־צְבָא֔וֹ נַחְשׁ֖וֹן בֶּן־עַמִּינָדָֽב.... (יח) וְנָסַ֗ע דֶּ֛גֶל מַחֲנֵ֥ה רְאוּבֵ֖ן לְצִבְאֹתָ֑ם וְעַ֨ל־צְבָא֔וֹ אֱלִיצ֖וּר בֶּן־שְׁדֵיאֽוּר׃
(11) In the second year, on the twentieth day of the second month, the cloud lifted from the Tabernacle of the Pact (12) and the Israelites set out on their journeys from the wilderness of Sinai. The cloud came to rest in the wilderness of Paran.... (14) the first standard to set out, troop by troop, was the division of Judah.... (18) The next standard to set out, troop by troop, was the division of Reuben. In command of its troop was Elizur son of Shedeur;
R. Alter, Five Books of Moses: "After the preceding census lists, which provide the names of the tribal chieftains and then the head count of each of the tribes, with a stress on the census as a means of implementing military conscription, we are given a plan for the marching order of the Israelite forces, each tribe a military unit carrying its distinctive insignia.
...........................................................................
Alter assigns a role for these standards as military insignias which identified the various troops/tribes. The Midrash, cited by Rashi and others, found other meanings which linked them to previous figures and generations in Humash.
(א) באתת. כָּל דֶּגֶל יִהְיֶה לוֹ אוֹת מַפָּה צְבוּעָה תְלוּיָה בוֹ, צִבְעוֹ שֶׁל זֶה לֹא כְצִבְעוֹ שֶׁל זֶה, צֶבַע כָּל אֶחָד כְּגוֹן אַבְנוֹ הַקְּבוּעָה בַחֹשֶׁן, וּמִתּוֹךְ כָּךְ יַכִּיר כָּל אֶחָד אֶת דִּגְלוֹ;
דָּ"אַ: בְּאוֹתוֹת לְבֵית אֲבוֹתָם, בְּאוֹת שֶׁמָּסַר לָהֶם יַעֲקֹב אֲבִיהֶם כְּשֶׁנְּשָׂאוּהוּ מִמִּצְרַיִם שֶׁנֶּאֱמַר (בראשית נ') "וַיַּעֲשׂוּ בָנָיו לוֹ כֵּן כַּאֲשֶׁר צִוָּם, יְהוּדָה וְיִשָּׂשכָר וּזְבוּלוּן יִשָּׂאוּהוּ מִן הַמִּזְרָח, וּרְאוּבֵן וְשִׁמְעוֹן וְגָד מִן הַדָּרוֹם וְכוּ'", כִּדְאִיתָא בְתַנְחוּמָא בְּפַרָשָׁה זוֹ: (ב)
(1) באתת [EVERY MAN OF THE CHILDREN OF ISRAEL SHALL ENCAMP BY HIS OWN STANDARD] WITH THE SIGNS [OF THEIR FATHERS’ HOUSES] — Each banner shall have a different sign — a piece of coloured cloth hanging on it, the colour of the one not being the same as the colour of another, but the colour of each tribe shall be like that of his stone that is fixed in the breastplate (of. Exodus 28:21), and by this means everybody will be able to recognise his banner .
Another explanation of באתת לבית אבתם is: by the signs (i.e., following the signs) which their father Jacob gave them severally when they carried him out from Egypt, as it is said, (Genesis 50:12) “And his sons did unto him exactly as he had commanded them”. For he had commanded that Judah, Issachar and Zebulun should carry him, having their position at the east side of the bier, Reuben, Simeon and Gad at the south side, etc., — as it is related in Tanchuma on this section (Midrash Tanchuma, Bamidbar 12; cf. Rashi on Genesis 50:12).
(יב) וַיַּעֲשׂ֥וּ בָנָ֖יו ל֑וֹ כֵּ֖ן כַּאֲשֶׁ֥ר צִוָּֽם׃ (יג) וַיִּשְׂא֨וּ אֹת֤וֹ בָנָיו֙ אַ֣רְצָה כְּנַ֔עַן וַיִּקְבְּר֣וּ אֹת֔וֹ בִּמְעָרַ֖ת שְׂדֵ֣ה הַמַּכְפֵּלָ֑ה אֲשֶׁ֣ר קָנָה֩ אַבְרָהָ֨ם אֶת־הַשָּׂדֶ֜ה לַאֲחֻזַּת־קֶ֗בֶר מֵאֵ֛ת עֶפְרֹ֥ן הַחִתִּ֖י עַל־פְּנֵ֥י מַמְרֵֽא׃
(12) Thus his sons did for him as he had instructed them. (13) His sons carried him to the land of Canaan, and buried him in the cave of the field of Machpelah, the field near Mamre, which Abraham had bought for a burial site from Ephron the Hittite.
(א) באתת. סימנים היו בכל דגל ודגל. וקדמונינו אמרו שהיה בדגל ראובן צורת אדם מכח דרש דודאים. ובדגל יהודה, צורת אריה כי בו המשילו יעקב. ובדגל אפרים, צורת שור מטעם "בכור שור." ובדגל דן, צורת נשר. עד שידמו לכרובים שראה יחזקאל הנביא:
(1) ACCORDING TO THE ENSIGNS. There were signs upon each and every standard. The ancients said that the banner of Reuben had the form of a person on it. Their statement is based on a midrashic interpretation concerning the mandrakes found by Reuben. The ancients also tell us that there was an image of a lion on the standard of Judah, for Jacob had compared Judah to a lion. They also tell us that the banner of Ephraim had the image of an ox upon it, in keeping with the verse, His firstling bullock (Deut. 33:17). The flag of Dan had the image of an eagle. Thus the banners were similar to the cherubim which the prophet Ezekiel saw.
R. Milgrom, JPS Torah Commentary to Numbers: "standard" - Hebrew...probably originally meant a military banner.... This was later extended by association to include the army division, just as shevet and matteh, the two terms for "tribe," were probably derived from the "rod" that served as the official tribal insignia. The meaning "unit" better fits the context here...and is supported by the Targums and the Septuagint.... It comprised a garrison of 1,000 men that lived together with their families and...was an economic and legal unit as well as a military one....
"banners" - Here it means that each household had its distinctive insignia. According to Numbers Rabba...each tribe had a banner bearing the same color as its corresponding stone on the High Priest's breastplate....
