Midrash sa Mga Bilang 33:38: Mekhilta DeRabbi Yishmael, Ein Yaakov (Glick Edition), Shir HaShirim Rabbah & Seder Olam Rabbah

This tells me only of that period (i.e., the general period of the exodus.) Whence do I derive the same for succeeding periods? From (Ibid. 33:38) "in the fortieth year of the exodus of the children of Israel from the land of Egypt in the fifth month" (Av).

And thus we find that they went back (the distance of) three journeys (at Moses' behest), viz. (Numbers 33:8-10) "And they journeyed from Pi Hachiroth … And they journeyed from Marah and they came to Eilim … And they journeyed from Eilim and they encamped at the Red Sea." And thus we find that they went back eight journeys in honor of Aaron for his burial. As it is written (Devarim 10:6) "And the children of Israel journeyed from Be'eroth Benei Yaakan … There Aaron died, etc," Now did Aaron die in Mosera? Did he not die in Hor Hahar, viz. (Numbers 33:38) "And Aaron the Cohein went up to Hor Hahar, etc."? What, then, is the intent of "There Aaron died and he was buried there"? We are hereby apprised that they went back eight journeys in honor of Aaron for his burial, viz. (Numbers 33:31-37) "And they journeyed from Moseroth and they encamped in Benei Yaakan. And they journeyed from Bnei Yaakan and they encamped in Chor Hagidgad and they encamped in Yatvatha. And they journeyed from Yatvatha and they encamped in Avronah. And they journeyed from Avronah and they encamped in Etzyon Gaver. And they journeyed from Etzyon aver and they encamped in the desert of Sin, which is Kadesh. And they journeyed from Kadesh and they encamped in Hor Hahar, at the edge of the land of Edom."

Our Rabbis were taught: "There are six persons over whom the Angel of Death did not dominate: Abraham, Isaac, Jacob, Moses, Aaron, and Miriam. The first three because of the words mentioned, and the latter because it is written (Num. 33, 38) By the order of the Lord, etc. But concerning Miriam these words are not written? R. Elazar said: "Miriam also died the same death, because we infer it through the analogy by the word Sham Sham, and Scripture merely withheld it." Our Rabbis were taught: There are seven upon whom the worms have no domination: Abraham, Isaac Jacob, Moses, Aaron, Miriam, Benjamin ben Jacob; according to others, also David. The former six, because of the reasons stated above; and Benjamin, because it is written concerning him (Deut. 23, 12) The beloved of the Lord [is he], he shall dwell in safety, etc. There are four who died without sins of their own but [for the sin committed] through the instigation of the serpent; viz: Benjamin b. Jacob, Amram, father of Moses, Jesse, father of David, and Khiliab b. David. Concerning all of them we hold a tradition, except Jesse, the father of David, which is deduced from the verse, as it is written (II Sam. 17, 25) Now Amasa was the son of a man, whose name was Ithra the Israelite, that went in to Abigal, the daughter of Nachash, sister of Zeruiah, Joab's mother. Was she then the daughter of Nachash? Behold she was the daughter of Ithra as it is written (I Chr. 2, 16) And their sisters were Zeruiah, etc. We therefore say that it means who died through the instigation of the serpent.
