The sources specifically indicate that salt had a known use in the formation of covenants within the context of the Old Testament.

Salt Used in Forming Covenants

In the larger context of biblical instruction and practice, salt is referenced directly in relation to establishing or confirming covenants:

• Salt was used “in forming covenants”.
• The reference supporting this historical use points to the book of Leviticus (Leviticus 2:13).
• A “covenant of salt” is mentioned in the context of the dedication of the priesthood to God (Numbers 18:19).
• The concept of the “covenant of salt” also appears in connection with the covenant established with David’s dynasty (2 Chronicles 13:5).

The Larger Context of Salt

Beyond its role in covenants, the sources mention other functions and symbolic uses of salt, often emphasizing its positive, enduring, or protective qualities:

1. Purification and Preservation: Salt was used for “cleansing and preservation from decay”. This use is referenced in Ezekiel 16:4.

2. Flavor and Purpose: Salt was used for flavor (Job 6:6; Mark 9:50). Jesus drew on this common understanding to instruct his disciples:

• He declared to his followers, “You are the salt of the earth”.
• This statement emphasizes that the disciples’ lives should have a “profoundly positive effects on the world around them”.
• Jesus gave a corresponding warning about maintaining this role: if salt has “lost its flavor,” it is considered “worthless” and will be “thrown out and trampled under foot”. This warns disciples against doing anything that might “jeopardize that positive impact”.

3. Maintaining Integrity (Metaphorical Application): In the broader teachings of Jesus, the preservation property of salt is linked to the conduct required of his followers, who are called to a surpassing righteousness. The requirement for his disciples is to exhibit behavior that conforms to God’s will.
