Leviticus 6:20
This is the offering of Aaron and of his sons, which they shall offer unto the LORD in the day when he is anointed; the tenth part of an ephah of fine flour for a meat offering perpetual, half of it in the morning, and half thereof at night.
This is the offering of Aaron and of his sons, to be offered unto the LORD in the day of anointing, a tenth part of an ephah of fine flour for a continual meat offering, half of it in the morning and half of it at night, belonging to the morning and evening service of the earthly sanctuary. The meat offering is called perpetual, denoting what is continual or permanent in God's worship and service. It belongs to the ceremonial law instituted in consequence of sin, comprising the instructions about offerings and the priesthood and the sacrifices.
It is part of the provision in Leviticus 1-7 for individuals presenting their particular offerings during the year, within the complete yearly round of service in Leviticus 1-16 performed in the earthly sanctuary built by Moses in the wilderness, whose main features are described in Leviticus 1-7, 16 and 23. Those offerings brought day by day were joined with the daily offering and combined together in the continual daily ministration for the nation. That continual work was the daily service in the holy place, the first apartment, performed by the Levitical priesthood.
The offerings show God's hatred of sin and that sin demands a penalty, and as expressions of faith in the Redeemer to come they made constant remembrance of sin in the sanctuary while looking forward to a future antitype. When offered in faith by the sinner, the offering transferred in figure through the blood of the sacrifice or the person of the priest the penitent's sins to the sanctuary, leaving the forgiven sins there in figure when the blood was sprinkled upon the altar before the ark. This transferring work went on through the year until the tenth day of the seventh month, when the accumulated sins were cleansed out in the yearly Day of Atonement, the completion of the round of service fulfilled in the cleansing of the sanctuary.
The earthly sanctuary in its building, appointments, priesthood, and service was a pattern and shadow or type and impressive object-lesson of the heavenly sanctuary and Christ's more excellent ministry therein as High Priest and Minister, which Jesus began when He ascended on high and performed once for all, each year's service typifying His entire priesthood. That service reveals God's way, power, and glory, was not written in vain but is profitable for doctrine, reproof, correction, and instruction in righteousness to make the man of God perfect and was written for learning that through patience and comfort hope may be had. Study of the verse therefore enables understanding of the heavenly and gives clearer views of the Saviour and His work for men, since the offerings and sacrifices as types point to and typify Jesus Christ and His work.
