according to Wikipedia "Jesus and the woman taken in adultery", "most scholars agree that it was not part of the original text of John's Gospel."

The woman caught in adultery and brought to Jesus is not explicitly named in the Bible.

John 8:11 says that Jesus forgave the woman caught in adultery.

The issue would be adultery, but not who she was with.

None of his parables concerned adultery, but there were some notable passages that were.

In John chapter 8 there is the story of the woman about to be stoned for adultery; Jesus had her spared by telling the crowd that the one without sin could cast the first stone.

Also in John chapter 4 the Samaritan woman at the well was living with someone to whom she was not married.
