SALT
On the shores of the Dead Sea, salt of mediocre quality was obtained after the evaporation of salt water.
Salt was also obtained from which it adhered to the cliffs. The inhabitants of Canaan and the surrounding regions used salt to season their food and to preserve it (Jb. 6:6; Eclos. 39:26).
The Law commanded salt to be placed in all offerings (Lev. 2:13; Ez. 43:24; Ant. 3:9, 1). Lands impregnated with salt remain barren (Jb. 39:9).
The cities condemned to total destruction were sown with salt. Abimelech devastated Shechem and covered it with salt (Judg. 9:45).
During the cataclysm that destroyed the cities of the Arabah plain, Lot’s wife lingered in the cursed region and was transformed into a pillar of salt (Gen. 19:26; Ant. 1:11, 4).
The impure salt of Syria, exposed to rain, the sun, or deposited in damp houses, lost its flavor. Being of no use, it was thrown away (cf. Mt. 5:13; Lk. 14:35).
Salt, which gives pleasant flavor to food, is the symbol of the children of God, whose life and testimony should be full of flavor and attractiveness.
All the offerings of Leviticus, images of the offering of Christ, had to be presented with salt, which was a sign of the covenant with God (Lev. 2:13; cf. Ezek. 43:24).
The sacred perfume that was burned on the golden altar was to be salty (Ex. 30:35). The Lord Jesus told believers that they, in turn, were the salt of the earth (Mt. 5:13); they must have salt in themselves (Mark 9:51); His word must always be seasoned with salt (Col. 4:6).
In fact, there is nothing more flat, insipid, even deadly, than Christians without influence, lives without significance, words empty of meaning: they are totally useless things.
Other applications have been made of this symbol: just as salt stops corruption, believers are a brake on the corruption of the world; If salt causes thirst, authentic Christians should cause thirst for God in those around them.
