וַיָּבֹ֣אוּ בְנֵֽי־יִ֠שְׂרָאֵל כָּל־הָ֨עֵדָ֤ה מִדְבַּר־צִן֙ בַּחֹ֣דֶשׁ הָֽרִאשׁ֔וֹן וַיֵּ֥שֶׁב הָעָ֖ם בְּקָדֵ֑שׁ וַתָּ֤מָת שָׁם֙ מִרְיָ֔ם וַתִּקָּבֵ֖ר שָֽׁם׃
און די קינדער פֿון ישׂראל, די גאַנצע עדה, זײַנען געקומען אין מדבר צִן, אין ערשטן חוֹדש; און דאָס פֿאָלק איז געזעסן אין קָדֵש; און מרים איז דאָרטן געשטאָרבן, און איז דאָרטן באַגראָבן געװאָרן.
Rashi
כל העדה [THE CHILDREN OF ISRAEL], EVEN THE WHOLE CONGREGATION — The congregation in its entirety, for those who were to die in the wilderness in consequence of their sin had already died, but these had been expressly mentioned for life (cf. Rashi on v. 22).
Alshekh
The entire community of Bnei Yisroel came. The Midrash says that while Moshe and Aharon were busy with the burial of Miriam, they saw a multitude of the Bnei Yisroel coming. Aharon thought they were coming to do kindness with Miriam. However, Moshe told him that if so, they would have come with the elders leading the way, etc.
Alshekh
This teaches that the Bnei Yisroel should have done a kindness for Miriam, especially considering that they drank in the Wilderness in her merit. They realized this immediately upon her death and it was indisputable, for there had been many wells and they lived in Koidesh for many days, and suddenly the water disappeared.
