What were swaddling clothes used for in biblical times?

In biblical times newborn lambs that were destined to be sacrificed in the Temple, were wrapped in cloth strips (swaddling) to protect them from harm (sacrificial lams could not have blemishes). The Angel Gabriel came to the shepherds and told them they would recognize the newborn savior as he would be wrapped in swaddling. Jesus was the lamb of God, sacrificed for humanity's sins.
