Leviticus 2:13

It was applied to the bread offering for another reason because it symbolized the existence of an inviolable friendship between the host and the guest. It was to the Hebrew a perpetual memorial of the bond of union between Jehovah and Israel. Numbers 18:19. Hence the injunction, “Thou shalt not suffer the salt of the covenant of thy God to be lacking.”

With all… offerings… offer salt The typology of this requirement is explained by our Lord Jesus: “For every one shall be salted (purified or punished) with fire, (God’s holiness,) as every sacrifice shall be salted with salt.” See Mark 9:49, note.
