1. There shall none be defiled for the dead among his people—The obvious design of the regulations contained in this chapter was to keep inviolate the purity and dignity of the sacred office. Contact with a corpse, or even contiguity to the place where it lay, entailing ceremonial defilement (Nu 19:14), all mourners were debarred from the tabernacle for a week; and as the exclusion of a priest during that period would have been attended with great inconvenience, the whole order were enjoined to abstain from all approaches to the dead, except at the funerals of relatives, to whom affection or necessity might call them to perform the last offices. Those exceptional cases, which are specified, were strictly confined to the members of their own family, within the nearest degrees of kindred.

     4. But he shall not defile himself—"for any other," as the sense may be fully expressed. "The priest, in discharging his sacred functions, might well be regarded as a chief man among his people, and by these defilements might be said to profane himself" [BISHOP PATRICK]. The word rendered "chief man" signifies also "a husband"; and the sense according to others is, "But he being a husband, shall not defile himself by the obsequies of a wife" (Eze 44:25).

     5. They shall not make baldness upon their heads . . . nor . . . cuttings in their flesh—The superstitious marks of sorrow, as well as the violent excesses in which the heathen indulged at the death of their friends, were forbidden by a general law to the Hebrew people (Le 19:28). But the priests were to be laid under a special injunction, not only that they might exhibit examples of piety in the moderation of their grief, but also by the restraint of their passions, be the better qualified to administer the consolations of religion to others, and show, by their faith in a blessed resurrection, the reasons for sorrowing not as those who have no hope.
