Musar על ויקרא ד:ו

The reason the blood had to be sprinkled on the altar "seven times before the Lord," as the Torah states in 4,6, is connected to the deeper meaning of the number seven. The addition of the words: "before the Lord," may indicate that it addresses itself to G–d's anger, i.e. the face of the dividing curtain. Thus far the Rekanati.
