Luke 12:33–40

Verse 33. Be not solicitous that whilst you are fighting for the kingdom of heaven, the necessities of this life will be wanting to you, on account of his command. Sell what you possess, that you may bestow charity; which those do, who having left all things, nevertheless labour with their hands for their livelihood, and to bestow the rest in charity. Ven. Bede.

Verse 35. Let your loins be girded; that is 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. Theophy.

Verse 38. In the first watch is childhood, the beginning of our existence, and by the second is understood manhood, and by the third is meant old age. He, therefore, who does not comply with our divine Master’s injunctions in the first or second watch, let him be careful not to lose his soul by neglecting to be converted to God in his old age. Saint Gregory in Saint Thomas Aquinas

Verse 39. Some have imagined that the devil, our implacable enemy, is designated by the thief, and our souls by the house, and man by the householder: yet this interpretation does not agree with what follows; for the coming of our Lord is compared to the thief, as if surprising us on a sudden. This latter opinion, therefore, seems to be the more probable one. Theophylactus.
