Leviticus 4:16

וְנֽוֹדְעָה הַֽחַטָּאת אֲשֶׁר חָטְאוּ עָלֶיהָ וְהִקְרִיבוּ הַקָּהָל פַּר בֶּן־בָּקָר לְחַטָּאת וְהֵבִיאוּ אֹתוֹ לִפְנֵי אֹהֶל מוֹעֵֽד

when the sin wherein they have sinned is known, then the assembly shall offer a young bullock for a sin-offering, and bring it before the tent of meeting.

וְסָמְכוּ זִקְנֵי הָעֵדָה אֶת־יְדֵיהֶם עַל־רֹאשׁ הַפָּר לִפְנֵי יְהוָה וְשָׁחַט אֶת־הַפָּר לִפְנֵי יְהוָֽה

And the elders of the congregation shall lay their hands upon the head of the bullock before the LORD; and the bullock shall be killed before the LORD.

וְטָבַל הַכֹּהֵן אֶצְבָּעוֹ מִן־הַדָּם וְהִזָּה שֶׁבַע פְּעָמִים לִפְנֵי יְהוָה אֵת פְּנֵי הַפָּרֹֽכֶת

And the priest shall dip his finger in the blood, and sprinkle it seven times before the LORD, in front of the veil.

וּמִן־הַדָּם יִתֵּן עַל־קַרְנֹת הַמִּזְבֵּחַ אֲשֶׁר לִפְנֵי יְהוָה אֲשֶׁר בְּאֹהֶל מוֹעֵד וְאֵת כָּל־הַדָּם יִשְׁפֹּךְ אֶל־יְסוֹד מִזְבַּח הָעֹלָה אֲשֶׁר־פֶּתַח אֹהֶל מוֹעֵֽד

And he shall put of the blood upon the horns of the altar which is before the LORD, that is in the tent of meeting, and all the remaining blood shall he pour out at the base of the altar of burnt-offering, which is at the door of the tent of meeting.
