I was reading in my devotions a passage in Leviticus and wondered the reasons for no leaven and no honey in the grain burnt offering, but there was to be a salted" (see Lev 2:11-13]
I knew the symbolism of leaven and salt in the New Testament---and the NT gets much of its symbolism from the Old. So I checked one source and found it interesting:
"11. ye shall burn no leaven, nor any honey, in any offering of the Lord - Nothing sweet or sour was to be offered. In the warm climates of the East leavened bread soon spoils, and hence it was regarded as the emblem of hypocrisy or corruption. Some, however, think that the prohibition was that leaven and honey were used in the idolatrous rites of the heathen.
12. the oblation of the first-fruits - voluntary offerings made by individuals out of their increase, and leaven and honey might be used with these (Leviticus 23:17; Numbers 15:20). Though presented at the altar, they were not consumed, but assigned by God for the use of the priests.
13. every . . . meat offering shalt thou season with salt - The same reasons which led to the prohibition of leaven, recommended the use of salt - if the one soon putrefies, the other possesses a strongly preservative property, and hence it became an emblem of incorruption and purity, as well as of a perpetual covenant - a perfect reconciliation and lasting friendship. No injunction in the whole law was more sacredly observed than this application of salt; for besides other uses of it that will be noticed elsewhere, it had a typical meaning referred to by our Lord concerning the effect of the Gospel on those who embrace it (Mark 9:49, 50); as when plentifully applied it preserves meat from spoiling, so will the Gospel keep men from being corrupted by sin. And as salt was indispensable to render sacrifices acceptable to God, so the Gospel, brought home to the hearts of men by the Holy Ghost, is indispensably requisite to their offering up of themselves as living sacrifices [BROWN].""
I love the picture it gives of needing incorruption, no hypocriasy, and the fact that the Gospel acts as a preservative to maintain or keep us from the incorruption of sin. Numbers 18:19 refers to a covenant of salt--symbolizing the covenant between God and Israel---probably because salt signifies perpetual or eternal since it is indestructible by fire and a preserving agent.
