ואת כל דם AND ALL THE BLOOD — i. e. all the remainder of the blood (since part of it had already been sprinkled) (Zevachim 25a).

לפני ה׳ אשר באהל מועד before the Lord who is in the Tent of Meeting, etc. In answer to the question why the Torah had to write the words "before the Lord" which had already been written in verse 6, Rabbi Nechemyah in Torat Kohanim says that seeing that we find that Aaron stood beyond the golden altar on the Day of Atonement when he sprinkled the blood on the dividing curtain, we could have assumed that the same procedure was to be followed here. The Torah therefore had to make clear that only the golden altar was "before the Lord," not Aaron. This suggests that except for the fact that the blood of the bullock on the Day of Atonement was sprinkled towards the dividing curtain, the words "before the Lord" in our verse would be superfluous. This is difficult. How would I have known where Aaron was to have stood if the Torah had not written the words "before the Lord?" Seeing that in that event the Torah had not designated a specific spot where Aaron had to stand to perform the sprinkling ceremony, I would have concluded that he had the choice of standing either in front of the golden altar or beyond it. The Torah therefore had to write the words: "in front of the Lord," to tell us that Aaron was to stand in front of the altar. Why was all this necessary? Because we find that there was another occasion when he was to stand beyond the golden altar. Another difficulty is this: why would I assume that Aaron was to perform the ritual of sprinkling the blood towards the dividing curtain while he was standing so far away that the altar was between him and the dividing curtain? Perhaps the words are to tell us that he was to sprinkle the blood on the altar while standing in front of it (facing the dividing curtain)? Seeing that in Leviticus 17,18 the Torah describes Aaron as exiting the Holy of Holies in the direction of the golden altar while putting some of the blood of the bullock on its corners, maybe the Torah wanted to tell us that the same procedure should be followed here, i.e. that when Aaron was to put the blood on the corners of the golden altar he was to do so while having his back to the dividing curtain and facing outwards before pouring out the excess blood at the base of the copper altar? As far as the sprinkling of blood towards the dividing curtain was concerned, however, this should take place when Aaron stood between the golden altar and the dividing curtain? If we had had no other detail than this to worry about, we could have answered this problem.

The remaining blood. Although he already sprinkled from it, it is called “all the blood.” This teaches that the one who slaughters needs to receive all the bullock’s blood, as if it says: All the bullock’s blood he shall receive, and afterwards sprinkle. After the sprinkling, he pours the remaining [blood].
