וְהִזָּ֞ה מִדַּ֤ם הַחַטָּאת֙ עַל־קִ֣יר הַמִּזְבֵּ֔חַ וְהַנִּשְׁאָ֣ר בַּדָּ֔ם יִמָּצֵ֖ה אֶל־יְס֣וֹד הַמִּזְבֵּ֑חַ חַטָּ֖את הֽוּא׃
And he shall sprinkle of the blood of the sin-offering upon the side of the altar; and the rest of the blood shall be drained out at the base of the altar; it is a sin-offering.
Targum Jonathan on Leviticus
and he shall sprinkle some of the blood upon the side of the altar, and pour out the remainder of the blood at the foot of the altar: it is a sin offering.
