“And the Priest shall dip his finger in some of the blood, and sprinkle it seuen times before the Lord, euen before the vaile.”
1611 King James Version (KJV)
4:17 And sprinkle it - It was not to be poured out there, but sprinkled only; for the cleansing virtue of the blood of Christ was sufficiently represented by sprinkling. It was sprinkled seven times: seven is a number of perfection; because God made the world in six days, and rested the seventh. This signified the perfect satisfaction Christ made, and the compleat cleansing of our souls thereby.
