323. Come and see: In Egypt, it was written of their side, THE LAMB THEY WORSHIPPED, "eat not of it raw...but roast with fire," so its odor will rise. "Its head with its legs" (Shemot 12:9), in order to break and subdue it, so all that issue from that side may not rule. In the same manner it is written, "a red heifer, faultless without blemish..." (Bemidbar 19:2), that may subjugate all the sides of defilement so they may not rule.
324. Rabbi Aba said to him: But the red heifer is pure; why THEN COMPARE IT TO THE CALF AND THE LAMB, WHICH THE EGYPTIANS WORSHIPPED, AND WHY WILL ITS BURNING SUBDUE THE ASPECTS OF UNCLEANLINESS? He told him: It is so, THAT THE HEIFER ALLUDES ALSO TO THEIR SIDE, as explained that the heifer is comprised of the four kingdoms. "A heifer" is as is written, "For Yisrael is stubborn like a stubborn heifer" (Hoshea 4:16). "Red" alludes to the kingdom of Babylon, as it is written, "you are the head of gold" (Daniel 2:38), GOLD BEING RED. "Faultless" is the kingdom of Media. It is "without blemish," referring to the Greek kingdom. "Upon which never came a yoke" alludes to the kingdom of Edom, which was never under any yoke. The secret meaning is that though this verse was given several explanations, they all pertain to the same mystery.
325. We have studied the verse: "who can bring a clean thing out of an unclean? Not one" (Iyov 14:4). The secret of this verse is that THE RED HEIFER is a clean thing brought out of an unclean, because at first she was unclean, INCLUDING THE FOUR SAID KINGDOMS. Now that Judgment was executed on her and she was cremated by burning fire to become ashes, she is a clean thing out of an unclean, a clean thing brought out of an unclean.
326. Hence, all those who busied themselves with her became defiled indeed, BECAUSE SHE WAS UNHOLY. And though she turned into ashes, yet before being gathered and taken away, she defiles them all. And so it is written, "and he that gathers...shall wash his clothes, and be unclean..." (Bemidbar 19:10). Why DID SHE HAVE TO BECOME ashes? It resembles the verse, "And you shall tread down the wicked, for they shall be ashes under the soles of your feet" (Malachi 3:21), for when water was sprinkled upon the ashes, they became a clean thing out of an unclean.
327. The secret of this matter is the verse, "water of purifying (sin)" (Bemidbar 8:7), same as in "sin crouches at the door" (Beresheet 4:7). THE HEIFER IS ALSO A "SIN CROUCHES AT THE DOOR," and since she is a sin crouching at the door, it is written first, "That he may bring her outside the camp" (Bemidbar 19:3). Therefore, the work was given to the adjutant priest, and not to the High Priest. And a clean thing, out of an unclean, starts as impure and becomes pure. And all the aspects of the side of defilement, when they saw this, ran away and left that place. SHE THEREFORE PURIFIES THE UNCLEAN.
328. Therefore, she is of "water of purifying (sin)," and "water of sprinkling (unclean)," all of which is impure. Therefore, AFTER JUDGMENT WAS EXECUTED ON HER, the Holy Spirit had dominion. And the spirit of defilement surrendered all its power. The Judgment, EXECUTED on the spirit of defilement, was outside the camp. Since that spirit is defiled, it is written, "therefore shall your camp be holy" (Devarim 23:15). Rabbi Aba approached and kissed him.
