il s’en ira vers l’autel qui est devant le Seigneur, pour en faire la propitiation: il prendra du sang du taureau et de celui du bouc, en appliquera sur les cornes de l’autel, tout autour,
Mishnah Yoma
“And he shall go out to the altar that is before the Lord” (Leviticus 16:18): that is the golden altar. He then began to purify [the altar by sprinkling] in downward motion. From where does he begin? From the northeast horn [of the altar], then the northwest, then the southwest, then the southeast. From the place where he begins [sprinkling when offering] a sin-offering on the outer altar, there he completes [sprinkling] on the inner altar. Rabbi Eliezer says: he remained in his place and sprinkled. And on every horn he would sprinkle from below upwards, with the exception of the horn at which he was standing, which he would sprinkle from above downwards.
Mishnah Zevachim
If blood was mixed with water, if it retains the appearance of blood, it is fit [to be sprinkled on the altar]. If it was mixed with wine, we regard it as though it were water. If it was mixed with the blood of a beast or wild animal, we regard it as though it were water. Rabbi Judah said: blood cannot nullify blood.
