From today's Greek reading in Matthew 26:

Jesus tells the disciples one of them is going to betray him. They all freak and hope it isn't them. He tells one close to him that the guy whose hand goes into the dipping bowl at the same time his does is the one. Judas says, "It's not me, is it?" Jesus says, "You said it."

My musing: what was Jesus' expression as he had that little exchange with Judas?

A wink and a grin?

Incredible sadness.

And that is what can be fairly described as a brief discussion.
