The answer is: Swaddling clothes

Luke 2:7 - When a Jewish child was born, it was usual for it to be washed in water, rubbed in salt and wrapped in swaddling clothes, which are bands or blankets that confined the limbs closely. (Ezek 16:4)

When Jesus was born, he was wrapped in swaddling clothes, a custom that carried with it layers of meaning. In the ancient world, swaddling was not just about keeping a baby warm; it was also a way to symbolically prepare them for the world ahead. The practice traces back to the care Israelites often gave their newborns, emphasizing protection and nurturing right from the start.

Interestingly, swaddling clothing can be seen as part of a broader biblical theme of humility and simplicity. Jesus, the Son of God, enters the world not with grandeur, like a king, but rather in a way that many can relate to — amidst the familiarity of everyday life.

Ezekiel’s mention of wrapping newborns draws attention to how this care persists through time, and aligns with a healthcare tradition where salt is seen as a purifying agent. Salt in biblical times was also considered valuable; in fact, Roman soldiers were sometimes paid with salt, which was called “salary!" Seeing that Jesus connects to such a rich tradition early in his life underscores the message that divine paths often pave their way through ordinary beginnings.

Moreover, the angel’s proclamation that this child is a source of peace (Luke 2:14) resonates strongly with the idea that swaddling, as protective wrapping, symbolizes not just physical care but also the spiritual promise of peace and joy in the hearts of those who encounter him. This was the true opening act of his mission — transforming the mundane into the holy!
