And he shall take of the blood of the bullock, and sprinkle it with his finger upon the mercy seat eastward; and before the mercy seat shall he sprinkle of the blood with his finger seven times.

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.
