il apportera au pontife un bélier sans défaut, choisi dans le bétail, selon l’évaluation de l’offrande délictive; le pontife lui obtiendra grâce pour l’erreur qu’il a commise et qu’il ignore, et il lui sera pardonné.
Mishnah Parah
Lambs no more than one year old, And rams no more than two years old. And all these years are reckoned from day to day. One that is thirteen months old is not valid, neither as a ram nor as a lamb. Rabbi Tarfon called it palges. Ben Azzai called it noked. Rabbi Ishmael called it parakhrigma. If a man offered it he must bring for it the libation of a ram, but it is not counted as his offering. One that is thirteen months old behold it is a ram.
