📖 Biblical Definition
A salt covenant is an unbreakable agreement marked by the shared eating of salt — the symbol of preservation, purity, and indissoluble bond. Scripture names two salt covenants explicitly. The priesthood given to Aaron is one: "All the heave offerings of the holy things, which the children of Israel offer unto the LORD... it is a covenant of salt for ever before the LORD" (Numbers 18:19). The kingdom given to David is another: "the LORD God of Israel gave the kingdom over Israel to David for ever, even to him and to his sons by a covenant of salt" (2 Chronicles 13:5). Salt does not spoil; salt-covenants do not unravel. The pattern points to Christ — perfect Priest and eternal King — whose covenant is salted with His own blood.
📜 Webster 1828 Definition

Webster: salt — “the substance which gives the taste of seasoning to our food, and is used to preserve meats from putrefaction.”
Salt's preservative quality made it a fitting biblical symbol of covenant durability. To eat salt with another in the ancient Near East was to enter covenant; to break that covenant was a grave breach of hospitality and oath.

⚠️ Modern Corruption
Modern Christians know salt as flavor and preservative; we have lost it as the ritual sign of an unbreakable covenant.

Three Old Testament passages name a salt covenant: priesthood (Num 18:19), kingdom (2 Chron 13:5), and meat offering (Lev 2:13). In each, salt's preservative quality stands for the covenant's permanence.
Mark 9:50 gives the New Covenant version: have salt in yourselves, and have peace one with another. The salt of the covenant moves from the offering to the disciple. The household lives by salt now — preservative, savor, and bond.
