Leviticus 2
The grain offering (minchah) is the non-animal offering of the covenant worship system, prepared in one of four forms — uncooked fine flour, oven-baked loaves, griddle-cooked bread, or pan-cooked bread — all with olive oil and all without yeast or honey. A memorial portion (a handful of flour and oil with all the frankincense) is burned on the altar, producing the pleasing aroma; the remainder belongs to the priests, designated most holy. The absence of yeast and honey from the altar communicates the covenant's rejection of fermentation and natural sweetness as corrupting agents. Salt — the salt of the covenant — is required in every grain offering, communicating the covenant's permanent, incorruptible character. The firstfruits grain offering, made from crushed heads of new grain, is also addressed. The grain offering's structure — portion to God, portion to His servants — is the foundational model for the New Testament's principle of ministerial support.
Leviticus 2:1
When anyone brings a grain offering to the Lord, their offering is to be of the finest flour. They are to pour olive oil on it, put frankincense on it. The grain offering — minchah — is the non-animal offering that accompanies or stands alongside the burnt and peace offerings. The finest flour communicates the same standard as the unblemished animal: the best of what the offerer has. The oil poured on the flour and the frankincense placed on it are both fragrant and precious: the oil speaks of anointing and the Spirit's presence; the frankincense speaks of prayer ascending as fragrance. Revelation 8:4 describes the prayers of the saints as incense rising before God — the frankincense on the grain offering is the fragrant prayer-form of the covenant community's agricultural worship.
Leviticus 2:2
And bring it to Aaron's sons the priests. The priest shall take a handful of the flour and oil, together with all the frankincense, and burn this as a memorial portion on the altar, a food offering, an aroma pleasing to the Lord. The memorial portion — a handful of flour and oil plus all the frankincense — is the representative sample burned on the altar. The Hebrew azkarah means something that causes to remember or brings to mind. The handful burned is the portion that represents the whole before God; the frankincense burned with it sends up the fragrant prayer that accompanies the offering. The rest of the grain offering goes to the priests. The covenant economy: a portion for God, a portion for His servants, both from the same offering.
Leviticus 2:3
The rest of the grain offering belongs to Aaron and his sons; it is a most holy part of the food offerings presented to the Lord. The priests receive the remainder of the grain offering as their food — the portion that was not burned as the memorial. The most holy designation of the priests' portion communicates the sacredness of what they eat: the food of the priestly community is consecrated food, most holy. 1 Corinthians 9:13 says those who work in the temple get their food from the temple — the principle of the Levitical grain offering, where the priests live from the altar's offerings, is the foundation for the apostle's argument that those who preach the gospel should receive their living from the gospel.
