Tosefta para sa 1 Cronica 24:7

Four [Priestly] watches ascended from the exile: Yod'ayah, Charum, Pashchor, and Eimar. The prophets who were in Jerusalem divided them and installed them^*וחלקום והעמידום (GR"A), and made them into twenty-four watches, and they [inscribed their names on lots and] mixed them up and tossed them inside the ballot box. And Yod'ayah came and took out five, and with his own, behold, he had six. Charum came and took five, and with his own, behold, he had six. Pashchor came and took five, and with his own, behold, he had six. Eimar came and took five, and with his own, behold, he had six. And thus the prophets distributed [the watches] among them, for even should Yehoyariv (the head of the watches (see 1 Chron. 24:7) come up from the exile, Yod'ayah will not be displaced from its position; rather Yod'ayah will be the main [watch] and Yehoyariv will be secondary. The heads of the watches stood up and they affixed themselves to ancestral houses (see Taan. 2:6).
