John, the last apostle, dies at Ephesus
According to early church writers, John returned from Patmos to Ephesus after Domitian's death and lived into the reign of Trajan, the last of the Twelve to die. With him the apostolic age came to a close.
This is the disciple who testifies about these things, and wrote these things. We know that his witness is true.
John 21:24 (World English Bible)
Jesus had told Peter, “If I desire that he stay until I come, what is that to you?” and a rumor spread that John would not die; John's Gospel corrects it (John 21:22–23). Tradition says that in old age John would only repeat, “Little children, love one another.”
