Leviticus 4:25

וְלָקַ֨ח הַכֹּהֵ֜ן מִדַּ֤ם הַֽחַטָּאת֙ בְּאֶצְבָּע֔וֹ וְנָתַ֕ן עַל־קַרְנֹ֖ת מִזְבַּ֣ח הָעֹלָ֑ה וְאֶת־דָּמ֣וֹ יִשְׁפֹּ֔ךְ אֶל־יְס֖וֹד מִזְבַּ֥ח הָעֹלָֽה׃

καὶ ἐπιθήσει ὁ ἱερεὺς ἀπὸ τοῦ αἵματος τοῦ τῆς ἁμαρτίας τῷ δακτύλῳ ἐπὶ τὰ κέρατα τοῦ θυσιαστηρίου τῶν ὁλοκαυτωμάτων, καὶ τὸ πᾶν αἷμα αὐτοῦ ἐκχεεῖ παρὰ τὴν βάσιν τοῦ θυσιαστηρίου τῶν ὁλοκαυτωμάτων.

Y tomará el sacerdote con su dedo de la sangre de la expiación, y pondrá sobre los cuernos del altar del holocausto, y derramará la sangre al pie del altar del holocausto:

Then the priest is to take some of the blood of the sin offering with his finger, put it on the horns of the altar of burnt offering, and pour out the rest of the blood at the base of the altar.
