Σπαργανόω means to wrap in swaddling bands or strips of cloth, the ancient practice of binding infants snugly for warmth and perceived health benefits. Luke uses this term in the nativity narrative to describe Mary wrapping the newborn Jesus in strips of cloth and laying him in a manger. The detail serves multiple purposes: it shows Mary's maternal care even in difficult circumstances, emphasizes Jesus' genuine humanity and vulnerability, and provides a sign for the shepherds ('you will find a baby wrapped in cloths and lying in a manger'). The imagery recalls Wisdom 7:4's description of Solomon's humble birth.
