Midrasch zu Bereschit 46:17

They [the Israelites]--the entire congregation--came to the wilderness of Tzin in the first month, and the nation settled there, and Miriam died there and was buried there, and therre was not water for the congregation, and they gathered against Moses and Aaron (Numbers 20:1-2). When the well disappeared, it was Year 40, and it was the first of the month of Nissan, there in the episode when Moses sent messengers from Kadesh to the King of Edom (ibid. 20:14), and Israel made [themselves] there for 3 months. Aaron the Priest went up etc., and Aaron was 123 years old when he died at the hill of the mountain (ibid. 33). When Aaron died, the clouds of glory disappeared, and the Canaanites came to make war against Israel. The Canaanites, King of Arad, heard etc. (ibid. 33:40), but what hearing did he hear? He heard that Aaron died, and he the greatest scout traveled among them, and the cloud of glory disappeared, for he had fought for them, and he came to fight with them, and they retreated seven stations and camped at Moserah, for it says "The Israelites traveled from Be'erot Beney Ya'akan towards Moserah; there Aaron died" (Deuteronomy 10:6). Did Aaron die in Moserah? Lo, did he not die at the hill of the mountain? Rather, starting from the location where Aaron died, they retreated seven stations, until they encamped at Moserah, and, from there they traveled towards HaGidgad, etc. (ibid. 10:7), and, from there, towards Be'er etc. (Numbers 21:16), which is the well to which they returned. The Israelites traveled and encamped in Avot, and they traveled from Avot and encamped in Iyyey Ha'avarim etc., and from there they traveled and encamped at the Wadi Zered, and from there they traveled and encamped beyond Arnon etc. (ibid.). There they fought with Sihon, and Israel struck him with the sword etc., and they turned and arose on the path of Bashan etc., "and the Lord said to Moses: 'Do not fear him etc.' and they struck him and his children etc." (ibid.). "The Israelites traveled and encamped at Arvot Mo'av etc." (ibid. 22:1). "It was after the plague etc." (ibid. 26:19), "for these the land shall be divided etc." (ibid. 26:53), and, when staying in Arvot Mo'av, the children retreated to their parents, and their parents retracted and gave inheritance to their children. Serah bat Asher was among those who came to Egypt and those who left it. [She was] from those who came to Egypt, as it is written, "And Serah their sister" (Genesis 46:17), and [she was] from those who came to the Land [of Israel], as it says, "And there was the daughter of Asher, Serah" (Numbers 26:46). And Yokheved was among those who came to Egypt and those who left it. [She was] from those who came to Egypt, as it is written, "And the name of the wife of Amram was Yokheved, daughter of Levi etc." (ibid. 26:59). Ya'ir son of Menasheh and Makhir son of Menasheh were born in the lifetime of our ancestor Jacob, and they died after the death of Moses our teacher, and Novach was among those born in Egypt, and he died after the death of Moses our teacher, and he was buried beyond the Jordan, but there was no man among them left etc. (ibid. 26:65).
