The answer is: Salt

2 Ki 2:21

In 2 Kings 2:21, we find an intriguing episode where the prophet Elisha tosses salt in the water at Jericho to purify it. Salt, often associated with preservation and flavor, takes on a different role in this biblical context, showing God's power to restore and bring life. Jericho was known for having water that was "bad" and contributed to the barren land around it. Throwing salt into the problematic waters was symbolic; it suggests a supernatural intervention and refreshes the lifeblood of the community.

Fun fact: Jericho is famously known as one of the oldest continuously inhabited cities in the world! It was also the first city the Israelites encountered when they crossed the Jordan River. Remember the story of Joshua? These narratives echo God's ongoing relationship with Israel and their journey to the Promised Land.

Did you know that salt was a vital substance in ancient times? In addition to being used for healing and purification, it was critical for food preservation. There's even an ancient saying, “to be not worth one's salt,” which stems from the practice of Roman soldiers being paid in salt—a material that held immense value.

Elisha's act offers deep metaphorical meanings. It illustrates how something seemingly small can evoke substantial change. Just like that salt, our small acts can have a lasting and transformative impact on the world around us.
