John 13:11

John subjoynes a reason why Christ made this exception, and points out who it was that he meant by this exception, even Judas the traitour. Whence learn, 1. Christ knows a reason for every thing he saith or doth, whether we know it or not; as here we see. 2. Albeit neither can men discern, nor ought they to judge hardly of others, who have not discovered themselves; yet Christ can distinguish betwixt true professours and latent hypocrites, and may let forth what he knoweth, when he pleaseth; for, he knew who should betray him, and therefore said this. 3. Were hypocrites and traitours in never so excellent a society, and never so like Saints in outward appearance, yet are they not clean in Christs account; for, Judas is excepted from among the clean by Christ, though he was among the Apostles, and nothing yet had visibly appeared. 4. Doctrine delivered in mixed societies ought to be well guarded, that the unclean (if there were but one of them) do not put out their hands to the allowance of the clean; for, Christ upon this ground makes the exception, for he know who should betray him, therefore said he, Ye are not all clean.
