זוהר ויקרא — דף לז ע”א

The Zohar continues to explain why the wicked of Israel cannot serve as messengers of punishment against other wicked men, through a parable of a clever man who mixed in with the watchman's men to escape punishment, and the watchman recognizes him and tells him: "you are not one of those who sinned against the king, you will be punished first," and they kill him. Thus Israel always comes from the side of the right, and never clings to the left, and King Solomon cries out about this: "the time when man ruled over man to his harm."<br />
<br />
Rabbi Elazar confirms that there is a right and a left, mercy and judgment: Israel to the right and idol-worshippers to the left, and even when Israel is wicked and subdued, it remains on the right and never clings to the left. This is why it is said: "save me with your right hand and answer me."<br />
<br />
From here the Zohar moves to the passage "and it came to pass on the eighth day," and asks why it says "for seven days he shall fill your hands" in precisely these terms. The answer: happy are the priests who are crowned with the crown of the holy King and anointed with the holy anointing oil, for a supreme oil is awakened "that waters all seven," and this oil is "the sum of all seven." This is why the Community of Israel is called "daughter of seven," for she is composed of the other six.<br />
<br />
When these seven complete the priests, one arrives at the Community of Israel, who is the eighth, and Aaron is commanded to offer a calf to atone for the sin of the calf he had committed, and so the priest is found "perfect in everything, in eight kinds of garments of honor." Aaron's act below awakens its counterpart above, and so all the worlds are blessed. The passage closes by explaining why the calf and the ram were offered precisely so: the calf for the first sin, and the ram by virtue of Isaac's ram, "in order to complete everything."
