Exodus chapter 29 A Midrash taught that when God so pleased, God called for atonement for the Golden Calf through a male agent, as in , with regard to the investiture of the Priests, “Take one young bullock (, par),” and when God so pleased, God called for that atonement through a female agent, as in , “That they bring you a red heifer (, parah), faultless, wherein is no blemish . . . .” A Baraita taught that a priest who performed sacrifices without the proper priestly garments was liable to death at the hands of Heaven.

Thus, the Gemara reasoned, when wearing their proper priestly garments, priests were invested with their priesthood; but when they were not wearing their proper priestly garments, they lacked their priesthood and were considered like non-priests, who were liable to death if they performed the priestly service. A Midrash asked: As reported that there already were 70 elders of Israel, why in , did God direct Moses to gather 70 elders of Israel? The Midrash deduced that when in , the people murmured, speaking evil, and God sent fire to devour part of the camp, all those earlier 70 elders had been burned up. The Midrash continued that the earlier 70 elders were consumed like Nadab and Abihu, because they too acted frivolously when (as reported in ) they beheld God and inappropriately ate and drank. The Midrash taught that Nadab, Abihu, and the 70 elders deserved to die then, but because God so loved giving the Torah, God did not wish to create disturb that time. The Mishnah explained how the priests carried out the rites of the wave-offering described in On the east side of the altar, the priest placed the two loaves on the two lambs and put his two hands beneath them and waved them forward and backward and upward and downward. The Sages interpreted the words of , "which is waved, and which is heaved up," to teach that the priest moved an offering forward and backward, upward and
