Have you ever wanted to know what salt in the Bible actually means? The Bible references salt mentioned over 40 times! In fact, one of the most recognizable verses about salt was spoken by Jesus. He said, in Matthew 5:13:
Salt in History
Salt has a long and storied history. It’s more than just a way to season our food. Salt has been used in many cultures, throughout the world and throughout history as a valuable commodity.
The word salary comes from an ancient word meaning “salt-money,” referring to a Roman soldier’s allowance for the purchase of salt. Someone who works hard to earn his pay is still said to be “worth his salt.”
Salt has even been used to express promises and friendship between people. It was even considered by the Greeks to be divine. In biblical times and, even today in many Arab cultures, if two men eat salt together, they are sworn to protect one another—even if they had previously been enemies. In some cultures, people throw salt over their shoulders when they make a promise.
King Abijah’s address in 2 Chronicles 13:5 mentions a a salt covenant:
Here, Abijah refers to the binding promise of the Lord to give Israel to David and his sons forever.
Salt in the Bible
Salt in the Bible is mentioned for its various uses and symbolism including a “salt covenant”, antiseptic, preservative, and binding agreements. Let’s take a look at some of these (and more!) and learn the uses and meaning behind salt in the Bible.
In Leviticus we learn the reason why salt is added to grain offerings
Why was salt so important to add to grain offerings?
Salt was an important part of the offering because it represented purity, preservation, and expense. Every sacrifice offered to God should be pure, should be enduring, and should have a cost.
As far as the cost, salt in the Bible was a valued commodity. It is one of the reasons God required it in a sacrifice. It was of importance to the people and seen as a great sacrifice to give up. In fact, salt was a necessity of life in the ancient times used by many cultures as a seasoning, preservation, disinfectant, for ceremonial offerings and unit of exchange.
So, when God required salt to be a part of their grain offering, it wasn’t just on a whim. It was symbolic. -It showed the relationship God wanted with his people and how God wanted his people to be the preservative of the earth.
The idea of this salt covenant is also shared in Numbers when Moses speaks to the priests about the covenant God made with them.
And again in 2 Chronicles 13:5 which references King David and the covenant of salt God made with him.
Both of these promises or covenants were seen as lasting covenants made by God because the sacrifice included salt.
Salt is used as a preservative, which means it was important for making things last longer. So, when we say, “covenant of salt”, it simply means that the covenant is perpetual and not to be broken, just as how salt preserves. More on this below.
Moses tells the Israelites to add salt to their offerings, and in the process, the people agree to a “covenant of salt forever before the lord.”
The Hebrew word for covenant, be ̆riyth, means an agreement between two parties, based in trust, to fulfill their ends of the deal. The two parties of the covenant, God and His people, exchange salt, a tangible symbol of loyalty and friendship, to show the permanent nature of their agreement. Through salt, God reveals His indissoluble relationship with those He loves.
The Jewish people have not forgotten their salt covenants with God. To this day, every Friday at sunset, many practicing Jews still dip their bread into salt to keep their agreement with God.
Ezekiel’s 43:23 also makes a reference to the symbolism of salt as a reminder to the priests of God’s never-ending commitment to His people.
Salt was used to preserve and slow decay.
Salt is an aseptic meaning free from contamination and harmful bacteria. Salt prevents infection. While it cannot cure an ailment, it can stop the spread. So, in ancient times they used salt to keep items from spoiling. In biblical times, the did not have the luxury of electricity or refrigeration, as we do today, so salt was used to prevent food from going bad.
When Lot’s wife looked back on her life of sin and decay with sorrow, she lost the preserving qualities that made her stand out in society. She became one with everything else around her-a warning to us all about what can happen when we turn our backs against God. She is a warning to us.
Jesus warns us not to be like Lot’s wife in as he speaks of the coming Kingdom.
We are to look forward to our new life in Christ and not back on our former lives of sin and miss the old ways.
As discussed, salt is used to preserve the freshness of food. We season meat with salt to keep it fresh, we pickle fruits and vegetables by adding salt and prevent them from perishing. Salt sustains life. It signifies faithfulness. Likewise, Jesus Christ represents salt: He preserves life, sustains life, and is faithful to His promises to us.
Salt as a Symbol of Friendship and Loyalty
According to ancient, and biblical customs, a bond of friendship was formed through the eating of salt. It was said that once you had eaten a man’s salt, you were their friend for life. God wanted every sacrifice to be a reminder of this desired relationship with us.
Why salt? Because the essence of salt is simple – it does not change. When you heat salt in water, you know it will dissolve. We add it to our food while cooking all the time.
However, if you evaporate the water off a dish that has been seasoned with salt, you end up with salt crystals.
In both Islam and Judaism, salt seals a bargain instead of just giving your word because of how endurable the quality of salt is. That is why salt symbolizes a long-lasting friendship and relationship between people.
Salt Adds Flavor
It is common knowledge that salt is a flavor-enhancing agent to food.
What does this have to do with us being “salt of the earth? Most people assume salt adds flavor to food.
Salty foods are full of flavor because they release sodium ions which break down cell walls in vegetables, fruits, and meats. As these cells break down, we can enjoy the natural flavors of the food. (See Spices in the Bible)
In Matthew 5:13, Jesus tells us
We are salt and light. Our presence is to uplift, enhance or bring out the beauty in people’s lives do not harm them by being destructive but instead helping others live their best life possible so they can see all that God has created around us truly beautiful with joy!
Salt as a Valuable Mineral
As referenced above, we learn about the free will offering of the people to include salt.
These offerings also included unleavened bread, birds, goats, sheep, and cattle. Salt in the Bible was always part of these offerings to show that they represented a covenant – a promise.
In addition, also mentioned above, salt was an expensive and highly valued mineral. Generally, God uses valuable items to signify His promises.
Salt Represents Trials in Life
To understand this verse, you need to remember that fire represents trials and difficulties. So, we as God’s people will be “salted “or put through trials in our lives.
Those trials are our sacrifice and if we are the salt and our flavor is still good, we will be preserved during those trials. And it’s those trials that we seem to grow the most in our faith, giving it all to God, thus reaching that deep relations God desires to have with us.
Salt and Our Speech
The passage shouldn’t be too difficult to decipher in light of what we’ve learned about salt in the Bible. Our speech with God and others should be corruption-free and full of spiritual wisdom; speaking truthfully and lovingly to all around us
Salt and Babies?
Ezekiel mentions an interesting practice using salt in the Bible. He describes rubbing newborns with salt as part of a baby’s care after delivery. This is more than traditional practice: midwives during biblical times used salt as a natural loofa for removing any vernix, as well as to prevent the growth of bacteria.
Salt in Incense
Salt is also added to the incense used in the tabernacle’s daily worship. The divine recipe includes spices and minerals like stacte, onycha, galbanum, frankincense — and sodium too. The sacred perfume stimulates the Israelites’ olfactory memories, signaling to their bodies, minds, spirits, and emotions the call to worship. God knew long before modern perfumers that salt unlocks a range of aromatic notes. Even today salt is added to scents to unearth fruity, floral, and citrus layers, as well as to accentuate the smokiness of woody aromas.
Salt and Light
Of course, the most well-known reference to salt in the Bible is Jesus’ Sermon on the Mount found in Matthew 5:13.Symbolism in the Bible- Food & Nourishment
Jesus is saying to his disciples and followers, you are the salt. I see you and God sees you as precious. You are valued. You are also what will preserve this world. You should be a preserving influence on your culture. Without your Godly influence, this world would be spoiled. Evil, disease, bacteria, whatever you may call it would conquer but because with God and His people being the salt, we will preserve and bring goodness.
This passage also mentions the flavor of salt “But if salt has lost its taste” …
In biblical times, if people noticed that salt lost its flavor or preserving qualities, they would simply throw it out on the streets, and it would be trampled in the ground by pedestrians. It was no longer good to them.
This passage should be a caution to us as Christians. If we are the salt of the earth, but lose our flavor (our influence, actions, preserving qualities for this world,) we lose our value for the Kingdom of God. This might sound harsh, but it is God’s warning to us. He wants us to live as people on a mission for him.
We are here to enhance the lives of others by living and speaking like Jesus. If we lose our “divine flavor” so to speak, then it is as if we have lost our “saltiness.” Our words are meaningless and useless. The ESV version says, “thrown out and trampled under people’s feet.” That’s a pretty strong reminder.
How to Be the Salt of the World
What does it mean to be the salt of this world? Does everyone have that calling or are some more qualified than others because they’ve been called by Jesus himself. The answer: every person can become an agent for spreading God’s grace and love in their communities through being Christ-like – kind, generous minded with boldness when needed!
Isn’t this beautiful? We are to share kindness and goodness with those around us, so in our own ways we can help ease their troubles. But at the same time salt can also lose its influence or flavor.
Luke 14:34-35 teaches salt can become useless for the soil or for the manure pile.
Salt is an essential ingredient for preserving, nurturing, and bringing out the flavor in food. In much similar way we are to be that savor of life – enhancing people’s ability experience God’s goodness through our own experiences with them.
Jesus called his disciples to be the salt of the earth. That includes us.
So, if you’re going to leave a taste in someone’s mouth after your conversation with them, will it be pleasant and flavorful or bland and forgettable-will they know where you stand with Jesus Christ?
What are some things that you can do right now “to purify” this world -as well as yourself-, such preserving the Word of God?
You may sometimes question your value in this world and feel like you have little impact on the earth or are weak. But just as a small kernel of salt bursting with flavor is powerful enough to preserve other foods, YOU have the power to flavor the earth and be salt of the earth for God’s Kingdom!
Finally, salt makes us thirsty and our thirst grows for the Word of God as we grow in our faith.

Can we still use salt in our world today to break curses as in what Elijah was told to throw in the water to break the curse?
Thursday 3rd of November 2022
Hi, Sharon - my biblical understanding is that was under the old law (before Jesus came to save) and does not apply. It's a great question to ask your Pastor, though! thanks for stopping by!
