This is the statute of the Torah that the Lord has commanded, saying: Speak to the children of Yisrael, and they shall take to you a red heifer, perfect, in which there is no blemish, and upon which a yoke has not been laid.
Torah Temimah: Sifrei Zuta — “Temimah” means perfect in redness. Or is it merely free of blemishes? But it already says “in which there is no blemish.”
English: Perfect in redness. Or is it only [that it must be] perfect regarding blemishes? But it already says “in which there is no blemish.”
Resolution of apparent redundancy to establish the redness standard.
“Temimah” requires that the heifer be uniformly red; even two black (or non-red) hairs disqualify it, beyond the ordinary rule of blemishes.
