John 21 - Amplified Study Bible

21:4 the disciples did not know. Perhaps the apostles did not recognize Jesus because they were preoccupied with their work, as Mary Magdalene had been with her sorrow (20:14). In addition, there was not much light at this time of day.

21:7 Peter . . . threw himself into the sea. John was the first to recognize the Lord; Peter was the first to act.

21:17 You know that I love You. Peter denied the Lord at least three times. Here, he affirmed his love for the third time.

21:20–21 the disciple whom Jesus loved. This is commonly considered to be John, the author of this Gospel.

21:24 This is the same disciple. This is basically John’s signature to his Gospel.

21:25 there are also many other things which Jesus did. The Gospel of John is truthful (v. 24), but it is not exhaustive.
