Meaning
See COVENANT OF SALT.
The chief source of salt in Palestine is from the extensive deposits near the "sea of salt" (see DEAD SEA), where there are literally mountains and valleys of salt (2Sam 8:13, 2Kgs 14:7, 1Chr 18:12, 2Chr 25:11). On the seacoast the inhabitants frequently gather the sea salt. They fill the rock crevices with sea water and leave it for the hot summer sun to evaporate. After evaporation the salt crystals can be collected. As salt-gathering is a government monopoly in Turkey, the government sends men to pollute the salt which is being surreptitiously crystallized, so as to make it unfit for eating. Another extensive supply comes from the salt lakes in the Syrian desert East of Damascus and toward Palmyra. All native salt is more or less bitter, due to the presence of other salts such as magnesium sulphate.
Salt was used not only as a food, but as an antiseptic in medicine. Newborn babes were bathed and salted (Eze 16:4), a custom still prevailing. The Arabs of the desert consider it so necessary, that in the absence of salt they batheir infants in camels' urine. Elisha is said to have healed the waters of Jericho by casting a cruse of salt into the spring (2Ki 2:20 f). Abimelech sowed the ruins of Shechem with salt to prevent a new city from arising in its place (Jud 9:45). Lot's wife turned to a pillar of salt (Ge 19:26).
Figurative:
Salt is emblematic of loyalty and friendship (see above). A person who has once joined in a "salt covenant" with God and then breaks it is fit only to be cast out (compare Matt 5:13, Mark 9:50). Saltness typified barrenness (Deut 29:23, Jer 17:6). James compares the absurdity of the same mouth giving forth blessings and cursings to the impossibility of a fountain yielding both sweet and salt water (Jas 3:11 f).
