This is the law for expiating the guilt of a national sin, by a sin offering. If the leaders of the people, through mistake concerning the law, caused them to err, when the mistake was discovered an offering must be brought, that wrath might not come upon the whole congregation. Observe, 1. It is possible that the church may err, and that her guides may mislead her. It is here supposed that the whole congregation may sin, and sin through ignorance. God will always have a church on earth; but he never said it should be infallible, or perfectly pure from corruption on this side heaven. 2. When a sacrifice was to be offered for the whole congregation, the elders were to lay their hands upon the head of it (three of them at least), as representatives of the people and agents for them. The sin we suppose to have been some common custom, taken up and used by the generality of the people, upon presumption of its being lawful, which afterwards, upon search, appeared to be otherwise. In this case the commonness of the usage received perhaps by tradition from their fathers, and the vulgar opinion of its being lawful, would not so far excuse them from sin but that they must bring a sacrifice to make atonement for it. There are many bad customs and forms of speech which are thought to have no harm in them, and yet may bring guilt and wrath upon a land, which therefore it concerns the elders both to reform and to intercede with God for the pardon of, Joe 2:16. 3. The blood of this sin-offering, as of the former, was to be sprinkled seven times before the Lord, Lev 4:17. It was not to be poured out there, but sprinkled only; for the cleansing virtue of the blood of Christ was then and still is sufficiently signified and represented by sprinkling, Isa 52:15. It was to be sprinkled seven times. Seven is a number of perfection, because when God had made the world in six days he rested the seventh; so this signified the perfect satisfaction Christ made, and the complete cleansing of the souls of the faithful by it; see Heb 10:14. The blood was likewise to be put upon the horns of the incense-altar, to which there seems to be an allusion in Jer 17:1, where the sin of Judah is said to be graven upon the horns of their altars. If they did not forsake their sins, the putting of the blood of their sin-offerings upon the horns of their altars, instead of taking away their guilt, did but bind it on the faster, perpetuated the remembrance of it, and remained a witness against them. It is likewise alluded to in Rev 9:13, where a voice is heard from the four horns of the golden altar; that is, an answer of peace is given to the prayers of the saints, which are acceptable and prevalent only by virtue of the blood of the sin-offering put upon the horns of that altar; compare Rev 8:3. 4. When the offering is completed, it is said, atonement is made, and the sin shall be forgiven, Lev 4:20. The promise of remission is founded upon the atonement. It is spoken here of the forgiveness of the sin of the whole congregation, that is, the turning away of those national judgments which the sin deserved. Note, The saving of churches and kingdoms from ruin is owing to the satisfaction and mediation of Christ.

If the whole congregation of Israel sin - This probably refers to some oversight in acts of religious worship, or to some transgression of the letter of the law, which arose out of the peculiar circumstances in which they were then found, such as the case mentioned Sa1 14:32, etc., where the people, through their long and excessive fatigue in their combat with the Philistines, being faint, flew on the spoil, and took sheep, oxen, and calves, and slew them on the ground, and did eat with the blood; and this was partly occasioned by the rash adjuration of Saul, mentioned Sa1 14:24 : Cursed be the man that eateth any food until evening.

The sacrifices and rites in this case were the same as those prescribed in the preceding, only here the elders of the congregation, i. e., three of the Sanhedrin, according to Maimonides, laid their hands on the head of the victim in the name of all the congregation.

When a ruler hath sinned,.... Or "prince", the "nasi", one that is lifted up above others in honour, power, and authority, or that bears the weight of government: the word comes from one which signifies to lift up, or to bear; it may be understood of a governor of a family, or of a tribe, as Aben Ezra observes; and so in the Talmud (k) it is said, it means the prince of a tribe, such as Nachson the son of Amminadab, prince of the tribe of Judah. Maimonides (l) says a king is designed, over whom none has power; and so Gersom on the place, who observes, that David the king is called a prince, Eze 34:24.

and done somewhat through ignorance against any of the commandments of the Lord his God; the phrase, "his God", is here added, and is not used neither of the anointed priest, nor of the congregation, nor of one of the common people; only of the prince, to show, that though he is above others, God is above him, and he is accountable to him; he is his God, of whom he is, and by whom he rules; wherefore if he breaks any of his commandments, though ignorantly, he must bring a sacrifice for it:

concerning things which should not be done, and is guilty; of transgressing negative precepts, which are as binding on him as others.

(k) T. Bab. Horayot, fol. 11. 1. (l) Hilchot Shegagot, c. 15. sect. 6.

if the whole congregation of Israel sin through ignorance--In consequence of some culpable neglect or misapprehension of the law, the people might contract national guilt, and then national expiation was necessary. The same sacrifice was to be offered as in the former case, but with this difference in the ceremonial, that the elders or heads of the tribes, as representing the people and being the principal aggressors in misleading the congregation, laid their hands on the head of the victim. The priest then took the blood into the holy place, where, after dipping his finger in it seven times, he sprinkled the drops seven times before the veil. This done, he returned to the court of the priests, and ascending the altar, put some portion upon its horns; then he poured it out at the foot of the altar. The fat was the only part of the animal which was offered on the altar; for the carcass, with its appurtenances and offals, was carried without the camp, into the place where the ashes were deposited, and there consumed with fire.
