Luke 12:35

Let your loins be girded; i.e. be prepared to walk in the way of virtue; a comparison taken from the custom of the eastern people, who girded up their long garments, when they went about any business. (Witham) --- After our divine Saviour had given his disciples such excellent instructions, he wishes to lead them still farther in the path of perfection, by telling them to keep their loins girt, and to be prepared to obey the orders of their divine Master. By lamps burning in their hands he wished to insinuate, that they were not to pass their lives in obscurity, but to let their lights shine before men. (Theophylactus)
