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 made his entrance into the world, the surroundings were modest, life was humble, and the wrapping that cloaked him spoke volumes about his circumstances. Swaddling clothes are more than just simple fabric; they symbolize care and protection. The fact that Mary wrapped her newborn son in such swaddling strips is reminiscent of how infants were often treated in Jewish culture, signaling that even though he was born in a stable, he was still enveloped in love.

Interestingly, this tradition echoes in other ancient texts. Just as close ties are being nurtured in priming young ones for life in a community, swaddling binds parents closer to their newborns emotionally and spiritually, indicative of a good Jewish upbringing. In Biblical times, swaddling also carried theological nuances - it's reflective not only of household customs but possibly even a touch of prophetic expectation about Jesus’ role as the "Suffering Servant," fitting that he began his life in such humble beginnings.

Additionally, in understanding the environments of the time, it is fascinating to note that the fields around Bethlehem were likely filled not just with shepherds but with rumbling livestock - hinting that the divine meets the mundane at every turn. What seems visually unremarkable becomes, in hindsight, pretty profound. The savior of the world—wrapped up just like any baby, indicating a connection that extends beyond socioeconomic boundaries. Each detail in the nativity narrative invites layers of significance, inviting reflection on purpose, humility, and kinship.
