Some Pharisees appear to help Jesus by letting him know that Herod is seeking to kill him–just a ruse in an attempt to get him to leave the area. Jesus’ response: “Go tell that fox, ‘I will keep on driving out demons and healing people…'” lets them know he knows exactly what they are thinking and it is unlikely that they are part of Herod’s inner circle!
Jesus goes on to lament for Jerusalem, “…how often I have longed to gather your children together…Look, your house is left to you desolate.” (see also Matthew 23:37-39.) We have some understanding of these words because we have the advantage of hindsight, the perspective that history allows us to have. At the time, Luke would not have known about the complete destruction of the temple that would come in the near future, but here we hear the words of Jesus, sad about what is to come.
