Ver. 70. I know not what thou sayest] He makes as if he understood not either her words or her meaning. And this false dissembling was a true denying. St Mark saith, that now the cock crew, Mark 14:68. A fair warning to so foul a sinner; but he took no notice of it, till Christ looked back upon him; to teach us, that without the help of divine grace, no means can convert a sinner from the error of his way.

Christ cured him with less ado than he did Malchus' ear, -that was healed by a touch, this by a look only.
