Bamidbar Rabbah

“Every male” – why “every male,” and it does not mention every female? It is because the glory of the Holy One blessed be He is exalted by the males. David said: “Behold, sons are a portion of the Lord; a reward, the fruit of one’s womb.” (Psalms 127:3). “Behold, sons are a portion of the Lord” – these are the males, but if the females came, they too are a reward.
“From one month old and above you shall count them” – why “from one month old and above”? Are they able to guard the Tent of Meeting from one month old? He Himself requests those who should guard it; why does He count “from one month old”? Rabbi Huna HaKohen said in the name of Rabbi Shmuel bar Ze’eira: It is in order to double their reward. Why? You find that they approach to serve only from thirty years old. Why then does He count them from one month old? It is so they will receive reward while they are still one month old.
Rabbi Huna HaKohen said in the name of Rabbi Shmuel bar Ze’eira: You find written in Samuel’s regard: “Samuel judged Israel all the days of his life” (I Samuel 7:15). Did Samuel judge Israel “all the days of his life”? But all the days of his life were only fifty-two years, and you find two during which he was nursing, forty years during which Eli was alive and judging, in which Samuel was unable to judge before his teacher, and two years that Saul ruled; that is forty-two. Ten years remained there; that is, he bore the burden of Israel for only ten years, but it is written: “Samuel judged Israel all the days of his life.” Rather, the Holy One blessed be He said: I am writing in his regard “all the days of his life” so that he will receive reward for all the days that he existed in the world. Regarding the tribe of Levi, too, the Holy One blessed be He said to Moses that he should count them from one month old and above, so that their reward would be calculated for them from one month old. That is, “from one month old and above you shall count them.”
Another matter: “From one month old” – Rabbi Yehuda HaLevi bar Rabbi Shalom said: The Holy One blessed be He is accustomed to be counting this tribe everywhere from when they are still young. From where is it derived? When the Holy One blessed be He said to Jacob to descend to Egypt, at that moment he counted his offspring; they all totaled sixty-six, as it is stated: “All the people were sixty-six” (Genesis 46:26). The two sons of Joseph and Joseph, that is sixty-nine. But it says: “All the people of the house of Jacob who came to Egypt were seventy” (Genesis 46:27). Rabbi Shmuel bar Naḥman said: The Holy One blessed be He is accustomed to count this tribe while they are still in their mother’s womb. Rabbi Berekhya HaKohen bar Rabbi said: This resin does not begin to emerge before one absorbs it;24As soon as it appears it is taken. Similarly as soon as the Levite appears, he is counted. so, Yokheved, her mother was pregnant with her at that moment, and she was in her mother’s womb and she was counted. Rabbi Shimon ben Lakish: Before her mother entered into the threshold of Egypt, she gave birth to her. That is why it is stated in her regard: “With seventy people your ancestors descended to Egypt.” (Deuteronomy 10:22). Regarding the children of her children as well: “Every male from one month old and above, you shall count them.” Why is it so? It is because this tribe is always beloved before the Holy One blessed be He. Of all the tribes, it is only this tribe alone that was chosen, as it is stated: “And chose it from all the tribes of Israel to be priests for Me” (I Samuel 2:28).
Rabbi Levi said: You find that there are many items that the Holy One blessed be He created in the world and he selected one of them for Himself. He created seven days, and the Holy One blessed be He chose Shabbat, as it is stated: “God blessed the seventh day and sanctified it” (Genesis 2:3). He created years, and selected one for Himself, as it is stated: “The land shall observe a Shabbat for the Lord; [.…the seventh year shall be a Shabbat of solemn rest for the land]” (Leviticus 25:2–4). He created seven-year cycles and selected one for Himself, as it is stated: “You shall sanctify the fiftieth year” (Leviticus 25:10). He created lands, and selected one of them for Himself, the Land of Israel, as it is stated: “The eyes of the Lord your God are always upon it” (Deuteronomy 11:12). Likewise, the Holy One blessed be He characterizes it as His land: “They divided My land” (Joel 4:2). He created heavens, and selected one of them for Himself; this is the highest heaven, as it is stated: “Praise Him who rides in the highest heavens” (Psalms 68:5). He created nations, and selected one of them for Himself; this is Israel, as it is stated: “And the Lord has chosen you to be a treasured people for Him” (Deuteronomy 14:2). He created tribes, and selected one of them for Himself; this is the tribe of Levi, as it is stated: “And chose it from all the tribes of Israel” (I Samuel 2:28). That is why the Holy One blessed be He said to Moses to count them from one month old, because He is exceedingly fond of them.
They raised an objection: According to these reasons, He should have counted them from one day old. Our Rabbis of blessed memory said: Why was it necessary to count them from one month old? It is because a one-day-old is not viable, but it is known that a one-month-old is viable; therefore, “from one month old and above you shall count them.” Alternatively, why were they counted from one month old? It is because the Levites were counted in this census only in order to redeem the firstborn of Israel. Just as the firstborn are redeemed from one month old, so the Levites were counted from one month old.

Pesikta DeRav Kahana

Rabbi Yochanan sat and expounded., "How did the water became for the Jews like a wall [at the splitting of the Sea]?" Rabbi Yochanan expounded, "It was like lattice-work." Serach bat Asher looked out and said, "I was there, and it wasn't like that - it was like a glass window." Rabbi Yochanan sat and expounded, "All the souls coming with Yaakov to Egypt, who came out of his loins, etc." (Genesis 46:26). With Yosef and his two sons, behold they are still lacking one (in order to add up to seventy)! Rabbi Levi in the name of R. Chama bar Chanina: "That is Yocheved, who was born at the gate of Egypt." And some say, "Serach bat Asher completed the number of Israel. 'I am one of those who seek the welfare of the faithful in Israel' (II Samuel 20:19). It is I that has completed the number of Israel. I have completed, being faithful for the faithful." Rabbi Tanchum bar Haanilai said, "The Holy One blessed be He Himself entered with them. And what is the explanation? 'He is your praise and He is your God' (Deuteronomy 10:21). What is written after it? 'Numbering seventy people, your forefathers went down to Egypt' (Deuteronomy 10:22)."

Midrash Tanchuma

(Numb. 3:15:) “Enroll the Children of Levi….” This text is related (to Ps. 68:7), “God causes individuals to dwell in a home.” A certain matron78Lat.: matrona. asked R. Jose ben Halafta, “In how many days [did the Holy One, blessed be He, create the world?” He said to her, “In six days, as stated (in Exod. 31:17), ‘for in six days the Lord made heaven and earth.’”79Gen. R. 68:4; Lev. R. 8:1; Numb. R. 3:6; PRK 2:4; below, Numb. 9:9; cf. above, Gen. 1:2. She said to him, “Ever since the world was created, what does He do?” “He sits [there] arranging marriages and issuing decrees. So He says, ‘So-and-so shall marry so-and-so.’” (Ps. 68:7), “God causes individuals to dwell in a home.” Who are they? This was Amram and his wife Yochebed, since through their merit the Holy One, blessed be He, brought Israel out of Egypt, where they had been enslaved with clay and bricks.80The Exodus theme is suggested by what follows in Ps. 68:7): HE BRINGS OUT THE PRISONERS INTO PROSPERITY, Cf. M. Pss. 68:4. What did the Holy One, blessed be He, do? He married Yochebed to Amram in order to raise up from them a redeemer for Israel and from them to raise up high priests. It is therefore stated (ibid.), “God causes individuals to dwell in a home.” The Holy One, blessed be He, said, “In as much as this tribe is accustomed to be raising up redeemers, go and number them.” (Numb. 3:15:) “Enroll the Children of Levi….” But it is written in another place (i.e., in Numb. 1:49), “However, you shall not enroll the tribe of Levi, nor shall you take a census of them.”81Cf. Numb. R. 3:7. When Israel had made the calf, what is written there (in Exod. 32:26)? “So Moses stood up in the gate of the camp and said, ‘Whoever is for the Lord, to me!’ And all of the sons of Levi gathered to him.” Hence the Holy One, blessed be He, said to Moses, (in the words of Numb. 3:15), “Enroll the Children of Levi.” R. Judah bar Shallum said, “The Holy One, blessed be He, is accustomed to numbering [the children of] this tribe in every case while they are young.82Numb. R. 3:8. How is it shown? When the Holy One, blessed be He, told Jacob to go down to Egypt, at that time he numbered Israel and his children; and all of them were found [to number] sixty-six, as stated (in Gen. 46:26), “And all the souls of the House of Jacob that came that came to Egypt… were sixty-six.” [In addition were] Joseph's two sons, plus Joseph, for a total of seventy minus one. But it says (in vs. 27), “all the souls of the House of Jacob, which came to Egypt, were seventy.” R. Levi said that R. Samuel bar Nahman said, “The Holy One, blessed be He, customarily numbers this tribe while they are in their mother's womb.”83Gen. R. 94:9 and M. Pss. 92:12. R. Berekhyah the Priest said, “There is not enough resin to flow out before they collect it.84Rt.: SPG; cf. the Gk.: spoggos (“sponges”). So it was in the case of Jochebed. Her mother was pregnant with her; and while she was in her mother's womb, she was numbered together with her.” Resh Laqish said, “While her mother was entering the gate of Egypt, her mother gave birth to her. The statement is therefore made concerning seventy souls (in Gen. 46:27).” And also concerning her children's children, the Holy One, blessed be He, said to Moses (in Numb. 3:15), “you shall enroll every male from the age of a month and upward.” Moses said to him, “Am I able to persevere and go around into their courtyards and into the midst of their houses to number each and every one of them, when You say (ibid.), ‘every male from the age of a month and upward?’”85Numb. R. 1:9. The Holy One, blessed be He, said to Moses, “You do your [part], and I will do my [part].” R. Judah bar Shalom the Levite said, “Moses would go and stand at the gate of the tent [in question]. Then the Divine Presence would draw near and say to him, ‘There are five infants in this tent; there are ten infants in that tent.’” Where is it shown? Where it is stated (in Numb. 3:16), “So Moses enrolled them according to the word (literally, according to the mouth) of the Lord, as he had been commanded,” [i.e.,] just as the Divine Presence told him.
