In these few verses in St. Luke, the writer plays on the animal vocabulary to describe two opposing groups. In the process it also echoes the exodus motif.
In this text, Herod is described as a fox. A fox is known for its cunning and deceitful ways. Herod wants Jesus out of his way. As N.T. Wright observes, “Herod is a predator.” The Pharisees come along and ask Jesus to flee the fox and exodus from the town. On the other hand, Jesus describes his purpose in gathering Israel to a hen protecting her own.
Herod wants to kick Jesus out and Jesus wants to kick demons out (exorcism). Jesus wants to gather his brood, but they will not listen. They do not want Jesus’ hen-like protection, and so they will suffer destruction. Their home will be left desolate. The glory will exodus from Israel’s temple. Jesus will journey out of the region, so that He may depart to Jerusalem. Finally, Jesus will work on day one and two, but on the third day He will depart and cry It is finished.
