ἁλίζω

I salt, sprinkle with salt, keep fresh and sound

Definition

ἁλίζω (alizō) means to salt, season, or preserve with salt. In its primary sense, it refers to the literal act of applying salt to something, often for the purpose of preservation, seasoning, or purification. In the New Testament, its sole occurrence is in Matthew 5:13, where Jesus tells his disciples, 'You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot.' Here, the verb is used metaphorically to describe the preserving and flavoring influence Christians are to have in the world. The concept also carries an ancient sacrificial connotation, as salt was used to purify and preserve offerings (Leviticus 2:13, Ezekiel 43:24).

Biblical Usage

This verb is used only once in the New Testament, in Matthew 5:13, within the Sermon on the Mount. It is employed in a metaphorical and proverbial saying by Jesus. There is no pattern of literal usage in the NT. The context is Jesus' teaching on the identity and mission of his followers, using the imagery of salt to illustrate their function in society.

Etymology

Derived directly from the noun ἅλας (halas, G217), meaning 'salt.' It is a denominative verb, meaning it is formed from a noun to indicate the action associated with that noun ('to salt'). The etymology is straightforward and directly related to its core meaning.

Semantic Range

This word is theologically significant as it anchors Jesus' central metaphor for Christian discipleship. Understanding ἁλίζω enriches the reading of Matthew 5:13 by connecting it to the Old Testament use of salt in covenants (Numbers 18:19) and sacrifices (Leviticus 2:13), symbolizing permanence, purity, and God's preserving grace. It teaches that believers are called to be a preserving influence against moral decay and to add gospel 'flavor'—truth and grace—to the world. A loss of this 'salty' quality renders one spiritually useless.

In the ancient world, salt was a vital commodity, primarily used to preserve food from spoilage in an era without refrigeration. It was also a symbol of covenant faithfulness and was used in ritual purification. When Jesus calls his followers 'salt,' his audience would have immediately understood the references to preservation, value, and covenant. The proverbial saying about salt losing its taste may refer to impure salt from the Dead Sea, which could become chemically inert, making it a fitting image for a disciple who abandons their distinctive calling.

ἅλας (halas, G217) — The noun 'salt,' the substance itself, from which the verb is derived.
