וְשָׁחַ֞ט אֶת־שְׂעִ֤יר הַֽחַטָּאת֙ אֲשֶׁ֣ר לָעָ֔ם וְהֵבִיא֙ אֶת־דָּמ֔וֹ אֶל־מִבֵּ֖ית לַפָּרֹ֑כֶת וְעָשָׂ֣ה אֶת־דָּמ֗וֹ כַּאֲשֶׁ֤ר עָשָׂה֙ לְדַ֣ם הַפָּ֔ר וְהִזָּ֥ה אֹת֛וֹ עַל־הַכַּפֹּ֖רֶת וְלִפְנֵ֥י הַכַּפֹּֽרֶת׃
I zarznie zagrzesznego kozła ludu, i wniesie krew jego za zasłonę i uczyni z krwią jego, jako uczynił z krwią cielca i pokropi nią ku wieku i przed wiekiem.
Mishnah Zevachim
Which is the place [for the offering] of the sacrifices?Most holy sacrifices are slaughtered on the north [side of the altar]. The bullock and the goat of Yom Kippur are [done] at the north, and the receiving of their blood is [performed] with ministering vessels at the north, and their blood requires sprinkling between the poles [of the ark], on the curtain, and on the golden altar. [The omission of] a single application of [the blood] invalidates [them]. He [the priest] would pour out the remainders of the blood on the western base of the outer altar, but if he did not pour it out, he did not invalidate [the sacrifice].
