What Does The Bible Say About Salt

Salt is an important ingredient of the natural world and has been used for centuries to preserve and flavor food. In the Bible, salt is mentioned many times and is presented in different ways. It often symbolizes an eternal covenant between God and his people, and can represent God’s unchangeable love and faithfulness.

In the Old Testament, salt was first mentioned in Leviticus 2:13, which states: “And every offering of your grain offering you shall season with salt; you shall not allow the salt of the covenant of your God to be lacking from your grain offering. With all your offerings you shall offer salt.” This passage is believed to foretell God’s covenant with the Israelites and his promise to be with them forever.

In the New Testament, Jesus says in the Gospel of Mark 9:50, “Salt is good, but if the salt has lost its flavor, how shall it be seasoned?” This verse is an allusion to a saying attributed to Jesus that likens faithfulness and good works to salt. In this context, Jesus is saying that those who are good and faithful to the Lord will remain salty and flavorful, while those who lose their faith will not.

One of the most famous mentions of salt in the Bible can be found in the Book of Matthew, where Jesus compares his followers to “the salt of the earth”. This statement is believed to be encouragement for his followers to be a source of light, to be wholesome and preserving forces in a world of darkness and evil.

The Bible also mentions salt in other contexts. For example, in Numbers 18:19, it is said that God commanded the Israelites to present offerings of salt to Him. This act is thought to represent their dedication and reverence for Him. In Ezekiel 16:4, God states that the Israelites lack knowledge due to not “eating salt with all their meals”. This verse is generally interpreted to mean that they do not have knowledge of God’s laws, or of the importance of living a righteous life.

Salt as a Sign of Friendship and Love

Salt has also been used throughout history to indicate friendship and love. In the Bible, the most famous verses that reference salt as a sign of friendship and love can be found in the Book of Ruth: “Your people will be my people, and your God my God. Where you go, I will go; where you stay, I will stay. Your people will be my people, and your God my God. Where you die, I will die, and there I will be buried… May the Lord do so to me and more also if anything but death parts me from you” (Ruth 1:16-17). Here, Ruth is expressing her devotion and faithfulness to her mother-in-law Naomi, and is essentially pledging her life to her. Her words are likened to a covenant of salt; an eternal, unchangeable bond filled with love and loyalty.

There are also several other verses in the Bible that reference salt as a sign of friendship and love. For example, Ezekiel 47:12 states “You will take for yourselves on the day you eat it, each man a perforated piece of bread. And in that day, when you will eat it, you will take an oath in my name. You will say, ‘I accept the oath in the name of the Lord’. Salt will also be in the bread.” This verse is interpreted to represent an unbreakable oath filled with divine protection and blessings.

Salt as a Teaching Tool

Saltt is also used in the Bible as a teaching tool. For example, Jesus states in the Gospel of Matthew 5:13, “You are the salt of the earth. But if the salt loses its flavor, how will it be made salty again? It’s no longer good for anything except to be tossed out and trampled on.” In this verse, Jesus is telling his disciples that they should be an example of righteousness and goodness, and that if they do not live up to these standards, they will be useless like salt that has lost its flavor.

In the Gospel of Luke 14:34-35, Jesus mentions salt again, saying “Salt is good, but if it loses its saltiness, how will you make it salty again? Have salt in yourselves and be at peace with each other.” Here, Jesus is emphasizing the importance of peace and unity in order to live in harmony with God and with each other. He teaches that it is through peace, truth, and understanding with one another that we will truly be made whole.

Salt is also mentioned in the Bible as an image of God’s grace and mercy. In Colossians 4:14, Paul says: “Let your speech be always with grace, seasoned with salt.” This verse is a reminder to the believers that they should use wisdom and grace when sharing the word of God and whenever they are communicating with others. It urges believers to be mindful of the words they choose and to use words that are filled with grace and kindness.

Salt as a Symbol of Purity

In ancient times, salt was used as a symbol of purity, cleanliness, and preservation. In Numbers 19:9-10, God commands the Israelites to use salt to purify themselves: “Take some hyssop, dip it in the water, and sprinkle it on the person who has become unclean. The person who has become unclean is to wash his or her clothes, shave off all their body hair, and bathe with water. Then they will be ceremonially clean.” This example of salt as a purifying agent is also referenced in Leviticus 2:13 where God commands the Israelites to never be “without the salt of the covenant of your God.” Here, salt is seen as a symbol of God’s covenant and gratitude towards his people.

In the Book of Proverbs, salt is mentioned several times as a symbol of purity and strength. In Proverbs 25:20, it states: “Like apples of gold in settings of silver is a word spoken in right circumstances.” This verse conveys that words should be given with careful consideration, and should be spoken with truth and purity. Likewise, Proverbs 9:8 says: “Do not correct a scoffer, lest he hate you; rebuke a wise man, and he will love you.” Here, Wisdom is portrayed like a type of salt, where wise words are like apples of gold in settings of silver and should be given to the wise.

Salt A Sign of Blessing and Protection

Salt is also seen in the Bible as a sign of blessing and protection. In 2 Chronicles 13:5, God commands the Israelites to use salt to protect and bless their altars: “You shall salt every offering of your grain offering with salt, and any offering of your burnt offering you shall not allow to lack salt.” This act is believed to be a blessing from God, for with salt comes protection and nourishment. Salt was also given to animals in the Bible as a sign of blessing, as mentioned in Leviticus 3:14-17: “And the priest shall sprinkle salt on all the offerings, he shall offer up the sacrifice, and burn it on the altar. And all its fat he shall offer up in smoke on the altar; and the breast shall be Aaron’s, and the right thigh shall be his.”

In 1 Chronicles 9:35, it is written that the priests also had salt on their tables during the offering of sacrifices. The Salt of the Covenant in this passage is interpreted to represent God’s blessing and protection over the consecrated altar.

Salt As a Form of Discipline and Judgment

In the Bible, salt is also mentioned in regards to judgement and discipline. In Job 6:6, it is written that Hope is “as sweet as dripping honey”, but Faithfulness and Righteousness are “as pungent as salt in a wound.” This verse stresses the importance of standing up for what is right, even when it is difficult and painful. Likewise, faithfulness and obedience to God are also likened to salt, as expressed in Proverbs 8:7: “The fear of the Lord is the beginning of knowledge.”

In Malachi 2:2, a similar metaphor is used to describe God’s judgement: “If you will not hear, and if you will not take it to heart, to give glory to my name, says the Lord of Hosts, then I will send a curse upon you, and I will curse your blessings. I will even turn them into a curse, because you do not give me glory.” Here, God is warning of the consequences of not giving glory to God and of not heeding his warnings, and is implying that his judgement will be harsh and lasting like salt.


As this overview has shown, salt is a recurring image in the Bible and can be used to represent several different themes and concepts. In the Bible, salt often represents purity, friendship, faithfulness, protection, judgement and discipline. By using salt as a metaphor, God communicates to humankind that love and loyalty will be rewarded, while those who disobey Him will be judged and cursed.
