Leviticus 16:14

וְלָקַח֙ מִדַּ֣ם הַפָּ֔ר וְהִזָּ֧ה בְאֶצְבָּע֛וֹ עַל־פְּנֵ֥י הַכַּפֹּ֖רֶת קֵ֑דְמָה וְלִפְנֵ֣י הַכַּפֹּ֗רֶת יַזֶּ֧ה שֶֽׁבַע־פְּעָמִ֛ים מִן־הַדָּ֖ם בְּאֶצְבָּעֽוֹ׃

καὶ λήμψεται ἀπὸ τοῦ αἵματος τοῦ μόσχου καὶ ῥανεῖ τῷ δακτύλῳ ἐπὶ τὸ ἱλαστήριον κατὰ ἀνατολάς· κατὰ τοῦ ἱλαστηρίου ῥανεῖ ἑπτάκις ἀπὸ τοῦ αἵματος τῷ δακτύλῳ.

Tomará luego de la sangre del becerro, y rociará con su dedo hacia la cubierta al lado oriental: hacia la cubierta esparcirá siete veces de aquella sangre con su dedo.

And he is to take some of the bull ’s blood and sprinkle it with his finger on the east side of the mercy seat; then he shall sprinkle some of it with his finger seven times before the mercy seat.
