Matthew Poole and continuators on Leviticus 4:6

6 And the Priest shall dip his finger in the blood, and sprinkle of the blood seven times n before the LORD, before the vail of the sanctuary.

To wit, the second vail, dividing between the Holy of holies, which is generally called by the name here used, as Exod. 26. 31, &c. and 35. 12. and 40. 3, 21. Numb. 4. 5.

m A number much used in Scripture, as a number of perfection; and here prescribed, either to shew that his sins needed more than ordinary purgation, and more frequent and manifest exercises of his faith and repentance, both which graces he was obliged to joyn with that ceremonial rite.
