In biblical times, salt held significant cultural and practical importance, extending beyond its culinary uses to various ceremonial and health-related applications. One such use was the practice of rubbing salt on newborn infants, a custom mentioned in the Scriptures that reflects the ancient understanding of salt's purifying and strengthening properties.

Biblical Reference:

The practice of salting newborns is explicitly mentioned in the book of Ezekiel. In Ezekiel 16:4 , God, through the prophet, describes the neglected state of Jerusalem using the metaphor of an unsalted infant: "On the day of your birth, your cord was not cut, nor were you washed with water to cleanse you; you were not rubbed with salt or wrapped in cloths." This passage highlights the customary care given to newborns, which included washing, salting, and swaddling, as acts of love and protection.

Cultural and Historical Context:

In ancient Near Eastern cultures, the act of rubbing salt on a newborn was believed to have several benefits. Salt was considered a purifying agent, symbolizing cleansing and protection from evil influences. The application of salt was thought to strengthen the skin of the infant, providing a form of early health care that was both practical and symbolic.

The use of salt in this context also reflects the broader biblical symbolism of salt as a covenantal and purifying substance. Salt was a key element in the offerings and covenants described in the Old Testament, symbolizing preservation, purity, and fidelity (Leviticus 2:13, Numbers 18:19).

Theological Implications:

From a theological perspective, the salting of infants can be seen as an early expression of the covenant relationship between God and His people. Just as salt was used to seal covenants and purify offerings, the salting of a newborn symbolized the hope for a life dedicated to God, marked by purity and strength.

Moreover, the metaphorical use of an unsalted infant in Ezekiel underscores the spiritual neglect and vulnerability of Jerusalem, contrasting the physical care expected for a newborn with the spiritual care God desired for His people. This imagery serves as a powerful reminder of the need for spiritual renewal and the protective care of God.

Practical Considerations:

While the specific practice of salting infants is not observed in contemporary Christian traditions, the underlying principles of care, protection, and dedication remain relevant. The biblical reference to this practice invites reflection on the ways in which believers are called to nurture and protect the vulnerable, both physically and spiritually, in accordance with God's covenantal love.

In summary, the use of salt for strengthening newborn infants in biblical times reflects a rich tapestry of cultural, symbolic, and theological meanings, emphasizing the importance of care, purification, and covenantal faithfulness in the life of God's people.Ezekiel 16:4
And as for your nativity, in the day you were born your navel was not cut, neither were you washed in water to supple you; you were not salted at all, nor swaddled at all.
