Salt of the earth

The phrase "Salt of the earth" typically refers to someone who is considered to be a very good, honest, and dependable person. It originates from the Bible, specifically in the Sermon on the Mount in the book of Matthew, where Jesus refers to his followers as the "salt of the earth." The phrase implies that such people add value, flavor, and preserve the goodness in society, much like salt does in food. It suggests an individual who is humble, reliable, and down-to-earth, often with strong moral character and virtues.
