Keep your loins girded

People in Jesus's culture wore long robes. They would tuck the bottom of the robes into their belts to keep them out of the way while they worked. Alternate translation: "Always be ready to serve" or "Be dressed and ready to serve"

and your lamps lit

"and keep your lamps burning." They were to be ready to work even at night.
