Jn 5:15 ... The man went-away and reported to-the Jews that Jesus is the-one having-made him healthy.

Verse 15 has the following 14 narrator words, ... apēlthen ho anthrōpos kai anēggeilen tois Ioudaiois hoti Iēsous estin ho poiēsas auton hugiē (Went-away the man and reported to-the Jews that Jesus is the-one having-made him healthy).

The 14 words are bottom up. Jesus warned the man to sin no more so that nothing worse happened to him. He was in a catch 22 situation. According to the authorities, if he unwittingly carried a burden (the mat) on the Sabbath, he had to bring a sin offering; if he carried the burden on purpose, he would be stoned to death. If the authorities found out he knew Jesus cured him and then concealed this information from them, he would be guilty of a greater crime (sin). When the man voluntarily reported to the authorities, he was informing on Jesus because that's what Jesus told him to do. The man obeyed Jesus both times.
