“You are the salt of the earth.” Salt has many uses. It preserves, purifies water, helps heal wounds and brings out flavors. In Jesus’ day, salt was particularly valuable. Privileged places at the table were closest to the salt. People have been paid in salt, the origin of the word salary. In the Old Testament, salt signified both our gift to God, bringing out flavor in the burnt offerings and salt was God’s gift to us, a sign of a lasting contract.(1) Salt has been a commodity for exchange, so valuable that merchants routinely traded it, even ounce-for-ounce with gold.
