Rujukan Mishnah untuk Imamat 6:5: Mishnah Berakhot & Mishnah Pesachim

From what time may one recite the Shema in the evening? From the time that the priests enter [their houses] in order to eat their terumah until the end of the first watch, the words of Rabbi Eliezer. The sages say: until midnight. Rabban Gamaliel says: until dawn. Once it happened that his sons came home [late] from a wedding feast and they said to him: we have not yet recited the [evening] Shema. He said to them: if it is not yet dawn you are still obligated to recite. And not in respect to this alone did they so decide, but wherever the sages say “until midnight,” the mitzvah may be performed until dawn. The burning of the fat and the pieces may be performed till dawn. Similarly, all [the offerings] that are to be eaten within one day may be eaten till dawn. Why then did the sages say “until midnight”? In order to keep a man far from transgression.

The [afternoon] tamid is slaughtered at eight and a half hours and is offered at nine and a half hours. On the eve of Pesah it is slaughtered at seven and a half hours and offered at eight and a half hours, whether it is a weekday or Shabbat. If the eve of Pesah fell on the eve of Shabbat it is slaughtered at six and a half hours and offered at seven and a half hours, and the pesah offering after it.
