צַ֚ו אֶת־בְּנֵ֣י יִשְׂרָאֵ֔ל וְאָמַרְתָּ֖ אֲלֵהֶ֑ם אֶת־קָרְבָּנִ֨י לַחְמִ֜י לְאִשַּׁ֗י רֵ֚יחַ נִֽיחֹחִ֔י תִּשְׁמְר֕וּ לְהַקְרִ֥יב לִ֖י בְּמוֹעֲדֽוֹ׃
Прикажи сынам Израилевым и скажи им: пищу Мою, которую Мне приносят для подношений огнем, от сладкого вкуса Мне, вы будете соблюдать, чтобы приносить Мне в должное время
Tosefta Ta'anit
Moses instituted eight watches for the Priesthood, and eight watches for the Levites. Once David and Samuel the Seer rose up, they made them into twenty-four Priestly watches and twenty-four Levitical watches, as it is said (1 Chr. 9:22), "[David and Samuel the Seer] established them in their office of trust" -- these are the Priestly and Levitical watches. The prophets that were in Jerusalem rose up and affixed there twenty-four posts [of Israelites] corresponding to the twenty-four Priestly and Levitical watches, as it is said (Num. 28:2), "Command the Children of Israel and say to them, My sacrifices, My food ... [you are to be vigilant in offering Me at their appointed time]." It is impossible to say that all of Israel [was tasked with this duty]; rather, it teaches that the agent of a person is like himself.
