Leviticus 4:6

את פני פרכת הקדש [AND THE PRIEST SHALL … SPRINKLE OF THE BLOOD …] BEFORE THE PARTITION VAIL OF THE קדש — i.e. before that spot where it is exceedingly holy — exactly in front of the space between the staves of the Ark (Sifra, Vayikra Dibbura d'Chovah, Section 3 10). The blood did not touch the Partition Vail (since he was standing some distance off), but if it happened to touch it, then it touched it, (and it did not invalidate the ceremony) (Yoma 57a).

וְטָבַ֧ל הַכֹּהֵ֛ן אֶת־אֶצְבָּע֖וֹ בַּדָּ֑ם וְהִזָּ֨ה מִן־הַדָּ֜ם שֶׁ֤בַע פְּעָמִים֙ לִפְנֵ֣י יְהֹוָ֔ה אֶת־פְּנֵ֖י פָּרֹ֥כֶת הַקֹּֽדֶשׁ׃

and the priest shall dip his finger in the blood, and sprinkle of the blood seven times before the Lord, before the veil of the sanctuary.
