Tosefta para sa Deuteronomio 7:20

Rabbi Yosei bar Rabbi Yehuda says, as soon as Israel left Egypt, they were appointed three worthy leaders, and they are Moses, and Aaron, and Miriam. Due to their merit, they were apportioned three gifts: The well, the column of cloud, and the manna. The well was due to the merit of Miriam, the column of cloud was due to the merit of Aaron, and the manna was due to the merit of Moses. When Miriam died, the well ceased to exist, but it was returned [to them] due to the merit of Moses and Aaron. When Aaron died, the column of cloud ceased to exist, but it was returned [to them] due to the merit of Moses. When Moses died, all three of them ceased to exist, and they were not returned [to them], as it is said (Zech. 11:8), "But I lost the three shepherds in one month, etc." And the hornet [that God had promised to send along with them to expel the Canaanites (Deut. 7:20)] did not cross the Jordan with them, rather, it stood on the banks of the Jordan and hurled its venom at them.
