13 And if the whole congregation of Israel err, and the thing be hid from the eyes of the assembly, and they have done any of the things which Jehovah hath commanded not to be done, and are guilty; 14 when the sin wherein they have sinned is known, then the assembly shall offer a young bullock for a sin-offering, and bring it before the tent of meeting. 15 And the elders of the congregation shall lay their hands upon the head of the bullock before Jehovah; and the bullock shall be killed before Jehovah. 16 And the anointed priest shall bring of the blood of the bullock to the tent of meeting: 17 and the priest shall dip his finger in the blood, and sprinkle it seven times before Jehovah, before the veil. 18 And he shall put of the blood upon the horns of the altar which is before Jehovah, that is in the tent of meeting; and all the blood shall he pour out at the base of the altar of burnt-offering, which is at the door of the tent of meeting. 19 And all the fat thereof shall he take off from it, and burn it upon the altar. 20 Thus shall he do with the bullock; as he did with the bullock of the sin-offering, so shall he do with this; and the priest shall make atonement for them, and they shall be forgiven. 21 And he shall carry forth the bullock without the camp, and burn it as he burned the first bullock: it is the sin-offering for the assembly.

Commentary on Leviticus 4:13-21

(Read Leviticus 4:13-21)

If the leaders of the people, through mistake, caused them to err, an offering must be brought, that wrath might not come upon the whole congregation. When sacrifices were offered, the persons, on whose behalf they were devoted, were to lay their hands on the heads of the victims, and to confess their sins. The elders were to do so, when the sacrifices were offered for the whole congregation. The load of sin was supposed then to be borne by the guiltless animal. When the offering is completed, it is said, atonement is made, and the sin shall be forgiven. The saving of churches and kingdoms from ruin, is owing to the satisfaction and mediation of Christ.
