John 6:71

He spake of Judas Iscariot the son of Simon: for he it was that should betray him, being one of the twelve.

Now he spoke of Judas, the son of Simon Iscariot, for it was he who would betray him, being one of the twelve.

Now he spake of Judas `the son' of Simon Iscariot, for he it was that should betray him, `being' one of the twelve.

And he spake of Judas, Simon's `son', Iscariot, for he was about to deliver him up, being one of the twelve.

He was speaking about Judas, the son of Simon Iscariot. For although Judas was one of the Twelve, he was later to betray Jesus.
