Isaiah 5:27

Luke 12:35

Verses 35,36. Let your loins, &c. This alludes to the ancient manner of dress. They wore a long flowing robe as their outer garment. Mt 5:38-41. When they laboured, 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. Comp. 2Kgs 4:29; 9:1; Jer 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. Comp. Mt 25:1 and Mt 25:2-13.

(f) "Let your loins" Eph 6:14, 1Pet 1:13 (g) "your lights burning" Mt 25:1,13

John 21:7

Verse 7. Therefore that disciple whom Jesus loved. Jn 13:23.

It is the Lord. He was convinced, perhaps, by the apparent miracle, and by looking more attentively on the person of one who had been the means of such unexpected and remarkable success.

His fisher's coat. His upper or outer garment or tunic, in distinction from the inner garment or tunic which was worn next the skin. In the case of Peter it may have been made of coarse materials such as fishermen commonly wore, or such as Peter usually wore when he was engaged in this employment. Such garments are common with men of this occupation. This outer garment he probably had laid aside.

He was naked. He was undressed, with nothing on but the under garment or tunic. The word does not require us to suppose a greater degree of nakedness than this. Mk 14:51, 1Sam 19:24.

Did cast himself into the sea. With characteristic ardour, desirous of meeting again his Lord, and showing his affection for him.
