Manifested himself ( εφανεροσεν εαυτον ). First aorist active indicative of  φανεροω with the reflexive pronoun (cf. 7:4; 13:4). For the passive see 1:31; 21:14. Jesus was only seen during the forty days now and then (Ac 1:3), ten instances being recorded. The word  φανεροω is often used of Christ on earth (Joh 1:31; 2:11; 1Pe 1:20; 1Jo 1:2), of his works (Joh 3:5), of the second coming (1Jo 2:28), of Christ in glory (Col 3:4; 1Jo 3:2).

At ( επ ). By or upon.

Of Tiberias ( της Τιβεριαδος ). As in 6:1 instead of the usual "Sea of Galilee." Tiberias, the capital city of Galilee, gave this epithet to the Sea of Galilee. This is not the appearance in Galilee prearranged by Jesus (Mr 16:7; Mt 28:7,16).

There were together ( ησαν ομου ). These seven (Peter, Thomas, Nathanael, the sons of Zebedee, and two others). We know that the sons of Zebedee were James and John (Mt 4:21), mentioned by name nowhere in John's Gospel, apparently because John is the author. We do not know who the "two others of his disciples" were, possibly Andrew and Philip. It seems to me to be crass criticism in spite of Harnack and Bernard to identify the incident here with that in Lu 5:1-11. There are a few points of similarity, but the differences are too great for such identification even with a hypothetical common source.

I go a fishing ( υπαγω αλιευειν ). The present active infinitive  αλιευειν expresses purpose as often. It is a late verb from  αλιευς (fisherman) and occurs in Jer 16:16, in Philo, Plutarch, and one papyrus. Peter's proposal was a natural one. He had been a fisherman by practice and they were probably waiting in Galilee for the appointed meeting with Christ on the mountain. Andrew and Peter, James and John were fishermen also. Peter's proposition met a ready response from all.

They took ( επιασαν ). First aorist active indicative of  πιαζω, Doric form for  πιεζω, to catch.

When day was now breaking ( πρωιας ηδη γινομενης ). Genitive absolute and note present middle participle (dawn coming on and still dark). In Mt 27:1 the aorist participle ( γενομενης ) means that dawn had come. For "beach" ( αιγιαλον ) see Mt 13:2.

Was ( εστιν ). Present indicative retained in indirect assertion.

Children ( Παιδια ). Diminutive of  παις and used here alone by Jesus in addressing his disciples. It is a colloquial expression like "my boys." The aged Apostle John uses it in 1Jo 2:13,18.

Have ye aught to eat? ( μη τ προσφαγιον εχετε; ). The negative answer is expected by this polite inquiry as in 4:29. The rare and late word  προσφαγιον from the root  φαγ ( εσθιω, to eat) and  προς (in addition) was used for a relish with bread and then for fish as here. So in the papyri. Nowhere else in the N.T.

The right side ( εις τα δεξια μερη ). Jesus knew where the fish were. For "net" ( δικτυον ) see Mt 4:20, here alone in John.

Were now not able to draw it ( ουκετ αυτο ελκυσα ισχυον ). Imperfect active picturing the disciples tugging at the net.

It is the Lord ( ο κυριος εστιν ). John's quick insight appears again.

Girt his coat about him ( τον επενδυτην διεζωσατο ). First aorist middle (indirect) indicative with which note  διεζωσεν εαυτον in 13:4. Apparently Peter threw on the upper garment or linen blouse ( επενδυτην ) worn by fishers over his waistcloth and tucked it under his girdle.

In the little boat ( τω πλοιαριω ). Locative case of  πλοιαριον (diminutive) for the larger boat ( πλοιον, verses 3,6) could come no closer to shore. But the words seem interchangeable in 6:17,19,21,22,24.

About two hundred cubits off ( ως απο πηχων διακοσιων ). For  πηχυς, cubit, see Mt 6:27 and for  ως απο see 11:18.

Dragging ( συροντες ). Present active participle of  συρω for which see Ac 8:3.

Got out ( απεβησαν ). As in Lu 5:2.

They see ( βλεπουσιν ). Vivid historical present.

A fire of coals ( ανθρακιαν ). See 18:18 for this word. Cf. our "anthracite."

There ( κειμενην ). Lying as placed, present middle participle of  κειμα.

Fish ( οψαριον ). As in 6:9,11, like  προσφαγιον above.

Laid thereon ( επικειμενον ). So broiling with bread ready (toast).

Which ( ων ). Ablative case by attraction from  α to agree with  οψαριων. They had caught the fish by Christ's direction.

Went up ( ανεβη ). Into the little boat or dinghy.

Drew ( ειλκυσεν ). Same verb as  ελκυσα in verse 6. Peter now did what they had failed to do.

Three ( τριων ). The addition "three" to the "hundred and fifty" looks as if they were actually counted these "large" ( μεγαλων ) fish. It was a great fish story that John recalls vividly.

Was not rent ( ουκ εσχισθη ). First aorist passive indicative of  σχιζω, to split (our word "schism").

Break your fast ( αριστησατε ). First aorist active imperative of  αρισταω from  αριστον, first to breakfast, as here and then later to dine as in Lu 11:37. What a delightful breakfast of fresh broiled fish just caught (verse 10) with the hush of joyful surprise in the presence of the Risen Lord.

Durst ( ετολμα ) Imperfect active of  τολμαω. The restraint of silence continued.

Taketh the bread, and giveth them ( λαμβανε τον αρτον κα διδωσιν αυτοις ). Vivid presents again. Jesus acts as host at this early breakfast, his last meal with these seven faithful followers.

Now the third time ( το ηδη τριτον ). "To the disciples" (apostles) John says, the two others being told by him (20:19,26) on the two Sunday evenings. There were four other appearances already (to Mary Magdalene, to the group of women, to the two on the way to Emmaus, to Peter).

Lovest thou me more than these? ( αγαπαις με πλεον τουτων; ). Ablative case of comparison  τουτων (disciples) after  πλεον. Peter had even boasted that he would stand by Christ though all men forsook him (Mr 14:29). We do not know what passed between Jesus and Peter when Jesus first appeared to him (Lu 24:34). But here Christ probes the inmost recesses of Peter's heart to secure the humility necessary for service.

I love thee ( φιλω συ ). Peter makes no claim here to superior love and passes by the "more than these" and does not even use Christ's word  αγαπαω for high and devoted love, but the humbler word  φιλεω for love as a friend. He insists that Christ knows this in spite of his conduct.

Feed my lambs ( Βοσκε τα αρνια μου ). For the old word  βοσκω (to feed as a herdsman) see Mt 8:33. Present active imperative here.  Αρνια is a diminutive of  αρνος (lamb).

Lovest thou me? ( αγαπαις με; ). This time Jesus drops the  πλεον τουτων and challenges Peter's own statement. Peter repeats the same words in reply.

Tend my sheep ( ποιμαινε τα προβατια ). Present active imperative of  ποιμαινω, old verb from  ποιμην (shepherd), "shepherd my lambs" ( προβατια, diminutive of  προβατον, sheep).

Lovest thou me? ( φιλεις με; ). This time Jesus picks up the word  φιλεω used by Peter and challenges that. These two words are often interchanged in the N.T., but here the distinction is preserved. Peter was cut to the heart ( ελυπηθη, first aorist passive of  λυπεω, to grieve) because Jesus challenges this very verb, and no doubt the third question vividly reminds him of the three denials in the early morning by the fire. He repeats his love for Jesus with the plea: "Thou knowest all things."

Feed my sheep ( βοσκε τα προβατια ). Many MSS. both here and in verse 16 read  προβατα (sheep) instead of  προβατια (little sheep or lambs).

Thou girdest thyself ( εζωννυες σεαυτον ). Imperfect active of customary action of  ζωννυω, old verb, in N.T. only here and Ac 12:8. So as to  περιεπατεις (walkedst) and  ηθελες (wouldest), two other imperfects of customary action.

When thou shalt be old ( οταν γηρασηις ). Indefinite temporal clause with  οταν and the first aorist active subjunctive of  γηρασκω, old verb to grow old, in N.T. only here and Heb 8:13, "whenever thou growest old."

By what manner of death ( ποιω θανατω ). Undoubtedly John, who is writing long after Peter's death, seems to mean that Peter was to die (and did die) a martyr's death. "Whither thou wouldest not." There is a tradition that Peter met death by crucifixion and asked to be crucified head downwards, but that is not made plain here.

Turning about ( επιστραφεις ). Second aorist passive participle of  επιστρεφω, old verb, here a sudden turning round (ingressive aorist). For the simplex verb  στρεφω see 20:14,16.

Following ( ακολουθουντα ). Following both Jesus and Peter, perhaps having heard the graphic dialogue above.

And what shall this man do? ( ουτος δε τι; ). Literally, "But this one ... what?" The abrupt ellipsis is intelligible.

If I will ( εαν θελω ). Condition of the third class with  εαν and the present active subjunctive of  θελω.

Till I come ( εως ερχομα ). Literally, "while I am coming" ( εως and the present indicative, not  εως ελθω (second aorist active subjunctive).

What is that to thee? ( τ προς σε; ). A sharp rebuke to Peter's keen curiosity.

Follow thou me ( συ μο ακολουθε ). "Do thou me keep on following." That lesson Peter needed.

That that disciple should not die ( οτ ο μαθητης εκεινος ουκ αποθνησκε ) (present active indicative), because Peter or others misunderstood what Jesus meant as John now carefully explains. He was rebuking Peter's curiosity, not affirming that John would live on till the Master returned. John is anxious to set this matter right.

That is ( ουτος εστιν ). The one just mentioned in verse 20, "the disciple whom Jesus loved."

And wrote these things ( κα ο γραψας ταυτα ). Here there is a definite statement that the Beloved Disciple wrote this book.

We know ( οιδαμεν ). The plural here seems intentional as the identification and endorsement of a group of disciples who know the author and wish to vouch for his identity and for the truthfulness of his witness. Probably we see here a verse added by a group of elders in Ephesus where John had long laboured.

If they should be written every one ( εαν γραφητα καθ' εν ). Condition of the third class with  εαν and present passive subjunctive of  γραφω, "If they should be written one by one" (in full detail).

I suppose ( οιμα ). Note change back to the first person singular by the author.

Would not contain ( ουδ' αυτον τον κοσμον χωρησειν ). Future active infinitive in indirect discourse after  οιμα. This is, of course, natural hyperbole, but graphically pictures for us the vastness of the work and words of Jesus from which the author has made a small selection (20:30f.) and by which he has produced what is, all things considered, the greatest of all the books produced by man, the eternal gospel from the eagle who soars to the very heavens and gives us a glimpse of the glory of God in the face of Jesus Christ.
