Charles Ellicott Commentary Leviticus 14:16

"and the priest shall dip his right finger in the oil that is in his left hand, and shall sprinkle of the oil with his finger seven times before Jehovah:" — Leviticus 14:16 (ASV)

And the priest shall dip. — The priest did not take the oil into the sanctuary, but, holding it in the hollow of his hand, stood in the court, while the officiating priest, turning his face to the Holy of Holies, dipped his right finger in the oil, and sprinkled it seven times upon the floor of the court, which was understood to mean “before the Lord,” dipping his finger every time he sprinkled the oil.
