Here "bathed" is a metaphor that means that God has cleansed a person spiritually. AT: "If anyone has already received God's forgiveness, he now only needs to receive cleansing from his daily sins" (See: [[rc://en/ta/man/translate/figs-metaphor]])
Jesus implies that the one who will betray him, Judas, has not trusted in him. Therefore God has not forgiven him of his sins. AT: "Not all of you have received God's forgiveness" (See: [[rc://en/ta/man/translate/figs-explicit]])
