Numbers 19:22

That is, unclean.

And whatsoever the unclean person toucheth shall be unclean,.... Not the person unclean by sprinkling, or touching the water of purification, but the unclean person spoken of throughout the chapter, that was unclean by touching a dead body, bone, or grave; whatever that man touched, any vessel or thing, that was unclean also; or "whomsoever", any person, man or woman, for it respects both persons and things:

and the soul that toucheth it; that which the unclean person hath touched; or "him", the unclean person, whether the unclean person touched him, or he the unclean person, or touched anything he had touched, he was unclean; denoting the spreading and infectious nature of sin, and how much sin and sinners are to be avoided; see Lev 15:4.

Is unclean, by touching the dead, must remain defiled seven days. But those whom he touches, as well as all who may have communication with them in infinitum, may be purified in the evening. (Calmet)

The unclean person; not he who is so only by touching the water of separation, Num 19:21, but he who is so by the greater sort of uncleanness, which lasted seven days, of which Num 19:11,16, and which was not removed without the use of this water of purification, as is manifest from the context and other places of Scripture, and from the nature of the thing; for the lesser sort of uncleanness, mentioned in the foregoing verse, lasted only till even, and was cleansed by the sole washing of his clothes and flesh in water, Num 19:7, without any use of this water of purification, which, if it had been necessary, must have been used on the third and on the seventh day, according to the rule, Num 19:12,19, and so the uncleanness of one day had been made an uncleanness of seven days, which is a contradiction. Besides it is unreasonable, that he who immediately touched the defiling thing, should be no more and longer unclean than he who touched that person only; and it was contrary to other rules in like cases, as Le 15, where the man or woman having an issue, are thereby made unclean for seven days, Lev 15:13,28, but he who toucheth them is made unclean only till even, Le 15:7,27. And therefore this cannot be meant of him who was unclean by touching this water, who himself was unclean only till even, Num 19:21, as also he who toucheth him is in this place.

Shall be unclean, to signify to us the very infectious nature of sin and of sinful company.

Until even, because as his defilement was less, so it was fit the duration of it should be shorter.

The unclean person - Not he who is so only by touching the water of separation, ver. 21, but he who is so by the greater sort of uncleanness, which lasted seven days, and which was not removed without the use of this water of purification.

וכל אשר יגע בו הטמא AND WHATSOEVER THE UNCLEAN PERSON TOUCHETH — i.e., this unclean person who has become unclean by reason of a corpse, SHALL TOUCH, יטמא SHALL BECOME UNCLEAN.

והנפש הנגעת AND THE SOUL THAT TOUCHETH him that hath become unclean by reason of a corpse,

תטמא עד הערב SHALL BE UNCLEAN UNTIL THE EVEN — Here we learn that a corpse is a progenitor of a primary source of uncleanness, and he that touches it becomes a primary source of uncleanness and can render a human being unclean. — This is its explanation (that of the whole chapter) according to what it literally implies and according to the Halachoth connected with it. — A Midrashic explanation I have copied from the work of R. Moses the Preacher, and this is:

ויקחו אליך AND THEY SHALL TAKE UNTO THEE — They shall take from that which is their own: just as they divested themselves of their golden earrings for making of the calf — i.e., of that which was their own, so shall they bring this calf-like animal as an atonement from that which is their own.

פרה אדמה A RED COW — Why this rite was performed with a cow may be exemplified by a parable it may be compared to the case of a handmaid’s child that defiled the king’s palace. They said: Let the mother come and wipe up the excrement. Similarly here: since they became defiled by a calf, let its mother (a cow) come and atone for the calf (cf. Midrash Tanchuma, Chukat 8).

אדמה RED — It had to be red in allusion to the idea contained in the text (Isaiah 1:18): “Though they (your sins) be red as scarlet [they shall become as white as snow]” — so you see that sin is termed red.

תמימה PERFECT — in allusion to the Israelites who were perfect but through it (the calf) became morally maimed: let this perfect animal come and atone for them so that they may regain their state of perfection.

לא עלה עליה על [A COW] UPON WHICH NEVER CAME A YOKE — just as they cast off themselves the yoke of Heaven.

אל אלעזר הכהן TO ELEAZAR THE PRIEST — just as they gathered together against Aaron who was a priest to force him to make the golden calf. But because Aaron had made the calf this rite was not entrusted to him that it should be carried out by him, because the prosecuting counsel cannot become the defending counsel (Rosh Hashanah 26a; cf. Rashi on Leviticus 16:4; Aaron who had caused the sin was not a fitting person to atone for it: therefore the rite had to be performed by another priest, viz., by Eleazar).

ושרף את הפרה AND ONE SHALL BURN THE COW, just as the calf was burnt (Exodus 32:20).

עץ ארז ואזוב ושני תולעת CEDAR WOOD AND HYSSOP AND CRIMSON — These three species correspond to the three thousand men who fell by the edge of the sword on account of the golden calf. The cedar is the loftiest of all trees and the hyssop the lowliest of all — a symbol that the man of high position who displays pride and on that account falls into sin should make himself as lowly as the hyssop and the worm (תולעת), and he will then gain atonement.

למשמרת [IT SHALL BE] KEPT [FOR THE CONGREGATION OF THE CHILDREN OF ISRAEL], just as the transgression of the calf is kept in remembrance for all future generations for punishment, for there is no visitation of Israel in which there is not something of the visitation of the sin caused by the calf, as it is said, (Exodus 32:34) “On the day when I visit I will visit [their sin upon them]” (cf. Rashi on that verse, and Sanhedrin 102a; Yerushalmi Taanit 14). And just as the calf rendered unclean everyone who busied himself with it (cf. Avodah Zarah 32b), so, too, does the cow make unclean all who busy themselves with it. And just as they (Israel) were purified by its dust (Exodus 22:20), similarly it states, (v. 17) “And for an unclean person shall they take of the dust of the burnt cow of purification, etc.”
