Leviticus 4:17

וְטָבַ֧ל הַכֹּהֵ֛ן אֶצְבָּע֖וֹ מִן־הַדָּ֑ם וְהִזָּ֞ה שֶׁ֤בַע פְּעָמִים֙ לִפְנֵ֣י יְהוָ֔ה אֵ֖ת פְּנֵ֥י הַפָּרֹֽכֶת׃

καὶ βάψει ὁ ἱερεὺς τὸν δάκτυλον ἀπὸ τοῦ αἵματος τοῦ μόσχου, καὶ ῥανεῖ ἑπτάκις ἔναντι Κυρίου κατενώπιον τοῦ καταπετάσματος τοῦ ἁγίου·

Y mojará el sacerdote su dedo en la misma sangre, y rociará siete veces delante de Jehová hacia el velo.

and he is to dip his finger in the blood and sprinkle it seven times before the LORD in front of the veil.
