e, pondo as mãos sobre a cabeça do bode vivo, confessará sobre ele todas as iniqüidades dos filhos de Israel, e todas as suas transgressões, sim, todos os seus pecados; e os porá sobre a cabeça do bode, e enviá-lo-á para o deserto, pela mão de um homem designado para isso.
Zohar
This is similar to the sacrifice of the scapegoat, of which it is written: "and he shall confess over him all the iniquities of the children of Yisrael" (Lev. 16:21). So here as well, (one should confess sins over every sacrifice). Because when the sacrifice is raised upon the altar it bears a twofold burden, each of which is raised to its own place. The first is the secret of man; the latter is in the secret of the beast, as it is written: "Hashem, You preserve man and beast" (Ps. 36:7).
