John 13:18-19

18I am not speaking of all of you. I know whom I have chosen; but [this has happened] in order that the Scripture may be fulfilled: ‘He who eats My bread has raised up his heel against Me [as My enemy].’

19From now on I am telling you [what will happen] before it occurs, so that when it does take place you may believe that I am He [who I say I am—the Christ, the Anointed, the Messiah].
