In chap. vi. 8-13 we have a "law of the burnt-offering" specially addressed to "Aaron and his sons," and designed to secure that the fire of the burnt-offering should be continually ascending unto God. In chap. i. we have the law regarding burnt-offerings brought by the individual Israelite. But besides these it was ordered, Exod. xxix. 38-46, that every morning and evening the priest should offer a lamb as a burnt-offering for the whole people,--an offering which primarily symbolised the constant renewal of Israel's consecration as "a kingdom of priests" unto the Lord. It is to this, the daily burnt-offering, that this supplementary law of chap. vi. refers. All the regulations are intended to provide for the uninterrupted maintenance of this sacrificial fire; first, by the regular removal of the ashes which would else cover and smother the fire; and, secondly, by the supply of fuel. The removal of the ashes from the fire is a priestly function; hence it was ordained that the priest for this service put on his robes of office, "his linen garment and his linen breeches," and then take up the ashes from the altar, and lay them by the side of the altar. But as from time to time it would be necessary to remove them from this place quite without the tent, it was ordered that he should carry them forth "without the camp unto a clean place," that the sanctity of all connected with Jehovah's worship might never be lost sight of; though, as it was forbidden to wear the priestly garments except within the tent of meeting, the priest, when this service was performed, must "put on other garments," his ordinary, unofficial robes. The ashes being thus removed from the altar each morning, then the wood was put on, and the parts of the lamb laid in order upon it to be perfectly consumed. And whenever during the day any one might bring a peace-offering unto the Lord, on this ever-burning fire the priest was to place also the fat, the richest part, of the offering, and with it also the various individual burnt-offerings and meal-offerings of each day. And thus it was arranged by the law that, all day long, and all night long, the smoke of the burnt-offering should be continually ascending unto the Lord.
