Tosefta sobre Levítico 16:9

[The High Priest] mixes up [the lots] in the urn and brings up the two lots, one in his right hand and one in his left hand. If [the lot "For Hashem"] came up in his right hand, all of Israel were joyous, and if it came up in his left hand, all of Israel were not joyous. They asked Rabbi Akiva, what if he switches them from left to right? He said to them, do not give [heretics] a chance to come down on you^*לרדות אחריהם (see Lieberman). Rabbi Yehuda says in the name of Rabbi Eliezer, the deputy and the High Priest would take out two in their right hands at once, and if [the lot "For Hashem"] was in the right hand of the High Priest, the deputy would ascend and say, "My Master, the High Priest, please raise your right hand." And if it was in the right hand of the deputy, the head of the house of the fathers would ascend and say, "My Master, the High Priest, please raise your left hand," and [thus the lots] were placed on the two goats. He says, "For Hashem," and the deputy says, "For a sin offering." Rabbi Yishmael says, he did not have to say "a sin offering." They said to him, is it not already stated (Lev. 16:9, JPS Tr.), "Which he is to offer as a sin offering"?
