Rabbi Aḥa said in the name of Rabbi Ḥanina: When Moses ascended on High, he heard the voice of the Holy One blessed be He, who was sitting and engaging in the portion of the red heifer and saying the halakha in the name of the one who said it. Rabbi Eliezer says: A calf within its first year, a heifer within its second year.43Mishna Para 1:1. He said before Him: ‘Master of the universe, may it be Your will that he be from my descendants.’ He said to him: ‘As you live, he is from your descendants.’ That is what is written: “And the name of one, Eliezer” (Exodus 18:4), the name of that special one.
