offering of the morning, which is for a daily burnt-offering." A baraita of the sages is then cited that orders the priority of those sacrifices from the preceding conversation: that of the bull of the anointed priest, the bull of the congregation, and the bull for an unwitting communal sin, and idol worship. The principal that all sin offerings precent burnt offerings is established. Likewise, it is taught that the goat sacrifice for idol worship precedes the goat of the king, because the communal precedes the individual (Hor. 13a). The Talmud continues the discussion about priority or precedence in circumstances of saving a life or rescuing an individual from captivity. The principal is stated that, "A Torah scholar precedes the king of Israel because in the case of a sage who dies we have no one like him, but in the case of a king of Israel who dies, all of Israel are fit for royalty." This overriding condition aside, the Talmud quantifies the priority of life in a hypothetical case where one life should be saved with triage decisions based on title or rank, such that higher priests or administrators in the Temple should have their lives be saved first. Similarly, a triage of life importance based on hierarchy of class is categorized such that the order is from highest to lowest: Priest, Levite, Israelite, mamzer, Nethinim, convert, and lastly the slave. The slave is last because of the curse of Ham. The overriding caveat to this discussion, however, was already provided by the Mishnah. This triage based on class hierarchy is only applicable if they are of equal wisdom, but a wise mamzer precedes others of higher social rank. Aggada Chapter 3 of Horayot unlike the previous two chapters includes narrative stories about the sages, or aggada. Horayot 10a tells the story of rabbi Gamliel and Rabbi Yehoshua on a boat journey. The story has been cited as the first periodic reference to Halley's Comet in world literature. The story is told that: The story from Horayot is a definite identification of a comet with an orbit of seventy years. Halley's Comet was seen in 66 CE when Rabban Gamaliel II and Rabbi Yehoshua, a.k.a. Joshua ben Hananiah, were beginning their careers as sages. Dr Jeremy Brown has stated that it is "both self-evident and beyond question" that Rabbi Yehoshua should be credited as the first to describe
