In the Bible record of Job, when he sorrows over the plain food he consumes during his sickness,
he says “Can that which is unsavory be eaten without salt?” (Job 6:6) In the lands and times of
the Bible, salt was used for seasoning and was the only available preservative besides the natural process of fermentation. In Mark 9:50, Jesus says “salt is good” when using it to illustrate a spiritual truth. It was a God ordained addition to His people’s diet. Cooked food was often
salted which was considered a symbol of honesty and faithfulness among parties that partook of
the meal.
Leviticus 2:13:
And every oblation of thy meat offering shalt thou season with salt; neither shalt thou
suffer the salt of the covenant of thy God to be lacking from thy meat offering: with all
thine offerings thou shalt offer salt.
1 Chronicles 13:5:
Ought ye not to know that the LORD God of Israel gave the kingdom over Israel to
David forever, even to him and to his sons by a covenant of salt?
Because of this symbolic usage of salt, it is used figuratively in the New Testament to convey
truthfulness or the idea of being faithful to your word.
Colossians 4:6:
Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought
to answer every man.
