Book of John - Chapter 13 - Verse 11

In this verse, Jesus is referencing Judas Iscariot, one of his disciples who would later betray him to the authorities. Jesus knew from the beginning who would betray him, as he had divine knowledge of all things. By stating "Ye are not all clean," Jesus is indicating to his disciples that not all of them are pure or faithful in their intentions towards him. This serves as a warning to them, particularly Judas, about the impending betrayal that would take place. It also highlights the importance of purity and loyalty in following Jesus and living out his teachings.
