the words "and he shall slay it before him" in to enjoin Eleazar not to divert his attention from the slaughter of the Red Cow. The Gemara reasoned that Samuel deduced that Eleazer must not divert his attention from the words "and the cow shall be burnt in his sight" in (which one could similarly read to imply an injunction for Eleazar to pay close attention). And Rav explained the words "in his sight" in one place to refer to the slaughtering, and in the other to the burning, and the law enjoined his attention to both. In contrast, the Gemara posited that Eleazar might not have needed to pay close attention to the casting in of cedar wood, hyssop, and scarlet, because they were not part of the Red Cow itself. Ulla interpreted the words "and he shall bring it forth" in to teach that he could not bring forth another cow with the Red Cow. As the Mishnah taught, if the Red Cow refused to go forth, one could not send a black cow with the Red Cow, lest people say that they slaughtered a black cow, nor could two Red Cows be brought forth together, lest people say that they slaughtered two. Rabbi (or others say Rabbi Jose) taught that a second cow was not to be taken out because says "and he shall bring it forth" and "it" implies by itself. The Gemara taught that the teaching of the Mishnah and Rabbi differed in the case of whether one could bring forth a donkey with the Red Cow. (According to the Mishnah, that would be permitted, because the presence of the donkey would not mislead people that they were sacrificing the donkey, but according to Rabbi, it would be forbidden, for "it" excludes permission for any other animal to be brought forth together with the Red Cow.) Ulla interpreted the words "And he shall slay it" in to teach that one could not slaughter any other one with it. A Midrash noted that God commanded the Israelites to perform certain precepts with similar material from trees: God commanded that the Israelites throw cedar wood and hyssop into the Red Cow mixture of and use hyssop to sprinkle the resulting waters of lustration in God commanded that the Israelites use cedar wood and hyssop to purify those stricken with skin disease in and in Egypt God commanded
