22.15 The word for ensnare comes from the root for trap (even anchor!), "pageh"
22.16 The literal phrase here is that his enemies "apostled their disciples," a reminder that Jesus is not the only one with apostles or disciples...
22.18 The word for hypocrite (a Greek word) means actor, or one who plays a part.
22.20 The word here for "head" or "portrait" here is literally "eikon," which means image. So the word is whose image. If it is a human head, the answer could just as easily have been "God."
