John 13:11 Meaning and Commentary

John 13:11

For he knew who should betray him
That is, Jesus, as Beza's ancient copy, and the Syriac and Persic versions read.

therefore, said he, ye are not all clean:
he does not mention his name, though he could have done so, it not being as yet proper to make so full a discovery of him, before the matter was ripe for execution; and also to put all the disciples upon examination of themselves.
