וְנָשָׂ֥א נֵס֙ לַגּוֹיִ֔ם וְאָסַ֖ף נִדְחֵ֣י יִשְׂרָאֵ֑ל וּנְפֻצ֤וֹת יְהוּדָה֙ יְקַבֵּ֔ץ מֵאַרְבַּ֖ע כַּנְפ֥וֹת הָאָֽרֶץ׃
И Он поставит знамя для народов, И соберет рассеянный Израиль, И соберет рассеянных Иудейских из четырех уголков земли.
Akeidat Yitzchak
The many flags that the Jews displayed in the desert will be replaced in messianic times by a single flag symbolising "One nation, One G'd." (compare Isaiah 11, 12-13) Ephrayim, though the "senior," whose encampment in the desert was behind the tabernacle, and who harboured resentment of that fact, will no longer have cause for such resentment. A single flag will serve the entire nation alike. There will no longer be a need to have visible symbols to help concentrate on the presence of G'd, His hashgachah, etc. Rivalry between various parts of the nation, i.e. Yehudah and Ephrayim will cease at that time.
