John 5:12 is the Jews' question that prompts this man's response — the cross-reference shows the immediate narrative context.

John 9:11 gives a similar healing testimony — the blind man explains how Jesus healed him, just as this healed man identifies his healer.

John 9:15 records a similar testimony to authorities — the blind man explains his healing, paralleling this healed man's report.

In John 9:34, the healed blind man is cast out by Pharisees—similar rejection faced by the man in John 5:15 after reporting to the Jews.

John 4:29 records another testimony — the Samaritan woman invites others to see Jesus, similar to the healed man reporting to the Jews.

In John 9:30, another healed man testifies about Jesus, echoing the pattern of witness from John 5:15.

In John 11:46, witnesses report Jesus' raising of Lazarus to Pharisees, similar to the healed man reporting in John 5:15.

Mark 1:45 describes a healed leper spreading the news widely — contrast with this man's report to the Jews that leads to persecution.

In Luke 13:14, a synagogue ruler objects to Jesus healing on the Sabbath, paralleling the Jewish leaders' persecution triggered by the report in John 5:15.
