Leviticus 2:1

1.And when any will offer. In this chapter Moses prescribes the rules for those offerings to which the name of minha is peculiarly given. They were not bloody sacrifices, nor offerings of animals, but only of cakes and oil. If any one would offer plain flour, he is commanded to season it with frankincense and oil, and also to choose fine flour, that the oblation may not be defiled by the bran. Thus here, as in all the service of God, the rule is laid down that nothing but what is pure should be offered; besides, by the oil its savor is improved, and by the frankincense a fragrant odor is imparted to it. We know that God is not attracted either by sweetness of taste nor by pleasant scents; but it was useful to teach a rude people by these symbols, lest they should corrupt God’s service by their own foolish inventions. Moses afterwards commands, that whatever is consecrated to God should be delivered into the hand of the priest, as we have before seen that private persons were excluded from this honor so that Christ’s peculiar dignity should remain to Him, i.e., that by Him alone access should be sought to God, and that all men might know that no worship pleases God except what He sanctifies. The substance of this type is shewn by the words of the Apostle, when he says that “by him” we now “offer the sacrifice of praise to God continually, that is, the fruit of our lips giving thanks to His name.” (Hebrews 13:15.) But when the priest had burnt a handful of the flour with the oil and frankincense, what remained was left for his own use; for, as we have elsewhere seen, the holy of holies of the burnt-offerings were given to the priests. Other kinds are then spoken of, viz., cakes, baken in the oven; then such as were fried in a pan; and thirdly, on a gridiron: for God would have the minha offered Him of every kind of cake, so that the Israelites might learn to look to Him in all their food, since nothing is clean to us except what He consecrates by His blessing. This is the reason why Moses accurately distinguishes between the cakes which were cooked either in the oven, or the frying-pan, or on the gridiron.
