Let your loins - This alludes to the ancient manner of dress. They wore a long flowing robe as their outer garment. See the notes at Matthew 5:38-41. When they labored, or walked, or ran, it was necessary to "gird" or tie this up by a "sash" or girdle about the body, that it might not impede their progress. Hence, to gird up the loins means to be "ready," to be active, to be diligent. Compare 2-Kings 4:29; 2-Kings 9:1; Jeremiah 1:17; Acts 12:8.
Your lights burning - This expresses the same meaning. Be ready at all times to leave the world and enter into rest, when your Lord shall call you. Let every obstacle be out of the way; let every earthly care be removed, and be prepared to follow him into his rest. Servants were expected to be ready for the coming of their lord. If in the night, they were expected to keep their lights trimmed and burning. When their master was away in attendance on a wedding, as they knew not the hour when he would return, they were to be continually ready. So we, as we know not the hour when God shall call us, should be "always" ready to die. Compare the notes at Matthew 25:1-13.

Let your loins - Be active, diligent, determined ready; let all hinderances be removed out of the way; and let the candle of the Lord be always found burning brightly in your hand. See on Luke 12:37 (note).

Let your loins be girded about,.... With the girdle of truth, Ephesians 6:14 keeping close to the doctrines of the Gospel, abiding faithfully by them, even unto death: the allusion is either to the eating of the first passover, Exodus 12:11 or rather to servants, who, in these eastern countries, wore long garments; and therefore, when in business, used to gather them up, and gird them about them, that they might perform their service with greater strength, more ease, quicker dispatch, and less hinderance: the phrase denotes readiness for business:
and your lights burning. The Vulgate Latin version adds, "in your hands"; meaning torches that were held in the hand: and may design either the Scriptures of truth, which were to be a light or lamp unto them, guiding and directing them in the ministration of the Gospel; or the lamps of profession, which should be kept clear and bright, and good works, becoming them, that should so shine before men, that all may see them, and glorify God. The allusion is to persons waiting at a wedding in the night, with torches and flambeaus in their hands.
