And the LORD said unto Moses, Speak unto the priests the sons of Aaron, and say unto them, There shall none be {a} defiled for the dead among his people:

(a) By touching the dead, lamenting, or being at their burial.

Wesley's Notes

21:1 Among his people - None of the priests shall touch the dead body, or assist at his funeral, or eat of the funeral feast. The reason of this law is evident, because by such pollution they were excluded from converse with men, to whom by their function they were to be serviceable upon all occasions, and from the handling of holy things. And God would hereby teach them, and in them all successive ministers, that they ought entirely to give themselves to the service of God. Yea, to renounce all expressions of natural affection, and all worldly employments, so far as they are impediments to the discharge of their holy services.

Jamieson-Fausset-Brown Bible Commentary

CHAPTER 21

Le 21:1-24. Of the Priests' Mourning.

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.

Matthew Henry's Concise Commentary

21:1-24 Laws concerning the priests. - As these priests were types of Christ, so all ministers must be followers of him, that their example may teach others to imitate the Saviour. Without blemish, and separate from sinners, He executed his priestly office on earth. What manner of persons then should his ministers be! But all are, if Christians, spiritual priests; the minister especially is called to set a good example, that the people may follow it. Our bodily infirmities, blessed be God, cannot now shut us out from his service, from these privileges, or from his heavenly glory. Many a healthful, beautiful soul is lodged in a feeble, deformed body. And those who may not be suited for the work of the ministry, may serve God with comfort in other duties in his church.
