Religious people were gathered in a religious place. When they heard that God directed help to be given to people of a different religion, they got furious, even violent.
In Luke's gospel Jesus will continue to face criticism from insiders when he helps outsiders. How much have attitudes changed? How do we react in similar circumstances?
Note that although Jesus escaped from the violence intended against him that day, his way did lead to the cross. Also note that the cross was not the final end of his work.
