John 21:7

“Therefore that disciple whom Jesus loved, etc.] Which was John the Evangelist and Apostle, the writer of this Gospel: saith unto Peter, it is the Lord; which two disciples were very intimate with each other, and communicated their thoughts freely to one another. John knew that it was the Lord, either by some special revelation, or from the multitude of fishes which were taken, and which showed a divine hand and power to be concerned. So faithful ministers of the Gospel know when Christ is with them, by his power attending their ministrations to the conversion of souls. The Cambridge copy of Beza’s reads, “our Lord”; as do the Syriac, Persic, and Ethiopic versions; and it is reasonable to…”

“that disciple whom Jesus loved, said, It is the Lord--again having the advantage of his brother in quickness of recognition (see on Joh 20:8), to be followed by an alacrity in Peter all his own. he was naked--his vest only on, worn next the body. cast himself into the sea--the shallow part, not more than a hundred yards from the water's edge (Joh 21:8), not meaning therefore to swim, but to get sooner to Jesus than in the full boat which they could hardly draw to shore.”

“Therefore that disciple whom Jesus loved - John, John 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…”

“Peter girt on his upper coat (for he was stript of it before) - Reverencing the presence of his Lord: and threw himself into the sea - To swim to him immediately. The love of Christ draws men through fire and water. John 21:12”

“21:7 “It’s the Lord!” John recognized Jesus, probably remembering that a miracle like this had happened before (Luke 5:1-11). • Peter, who had stripped off his clothes while working, put on his tunic in order to meet the Lord.”

“that disciple: Joh 21:20, Joh 21:24, Joh 13:23, Joh 19:26, Joh 20:2 It is: Joh 20:20, Joh 20:28; Psa 118:23; Mar 11:3; Luk 2:11; Act 2:36, Act 10:36; Co1 15:47; Jam 2:1 when: Sol 8:7; Mat 14:28, Mat 14:29; Luk 7:47; Co2 5:14 fisher's coat: Or, upper coat, great coat, or, surtout, επενδυτην \[Strong's G1903\], from επι \[Strong's G1909\], upon, and ενδυω \[Strong's G1746\], I clothe. naked: That is, he was only in his vest, or under garment; for γυμνος \[Strong's G1131\], naked, like the Hebrew arom is frequently applied to one who has merely laid aside his outer garment. See note on Sa1 19:24, and see note on Sa2 6:20. To which may be added what we read in the LXX, Job 22:6, "Thou has taken…”
