Midrash sa Mga Bilang 2:33: Bamidbar Rabbah

“These are those who were counted of the children of Israel…” (Numbers 2:32). Come and see how beloved Israel is before the Omnipresent, as the Holy One blessed be He wrote a tally of Israel four times in the context of the banners; twice individually⁴⁴By tribe. and twice generally. In addition, he counted each and every banner generally and individually, in order to inform how beloved they are before Him. They are His hosts and He wishes to count them all the time, like a person who has a treasure of which he is exceedingly fond. He counts it and counts it again many times, in order to arrive at its total, and he will rejoice over each and every count. So, the Holy One blessed be He is joyful with the mention of Israel’s tally, saying: ‘I have such and such hosts in My world who perform my will,’ and He takes comfort in them.
“And the Levites were not counted among the children of Israel, as the Lord commanded Moses” (Numbers 2:33).
“And the Levites were not counted…[as the Lord commanded Moses].” Just as it says in Israel’s tally: “As the Lord commanded Moses” (Numbers 1:19), as there was joy before the Omnipresent because the Levites were not counted with them, so that they would not be eliminated with them in the decree.⁴⁵They were not included in the punishment for the sin of the spies.

“The children of Israel did in accordance with everything that the Lord commanded Moses, so they encamped according to their banners, and so they traveled, each according to his families, by his patrilineal house” (Numbers 2:34).
“The children of Israel did in accordance with everything that the Lord commanded Moses.” The banners are beloved before the Omnipresent, as He wrote in their regard: “As the Lord commanded Moses” (Numbers 2:33), just as it is written regarding the labor of the Tabernacle.
“So they encamped according to their banners, and so they traveled, each according to his families, by his patrilineal house.” The verse tells that immediately, Israel was swift to fulfill the word of the Omnipresent regarding the banners, and did not hesitate to perform it.
“The children of Israel did….” Where was Aaron? Rabbi Yehoshua bar Rabbi Neḥemya and Rabbi Levi bar Ḥayata in the name of Rabbi Ḥiyya bar Abba: When he came to establish their lineage, Israel said to him: ‘You are establishing our lineage? Before you come to establish our lineage, go and establish the lineage of Elazar your son. To whom is he married? Is it not to the daughter of Putiel?’ That is what is written: “Elazar, son of Aaron, took from the daughters of Putiel as a wife” (Exodus 6:25). When the Holy One blessed be He saw that they were disparaging him, He accorded precedence to the honor of Aaron relative to the honor of Moses. That is what is written: “These are the generations [toldot] of Aaron and Moses” (Numbers 3:1).
