This Scripture gives a record if the last months of Jesus' earthly ministry. The Pharisees approached Jesus as He journeyed toward Jerusalem. Jesus was somehwere in the region of Ephraim, Perea and Bethany, preaching and teaching in the cities and villages. When the Pharisees had a conversation with Him concerning Herod the King. It would appear that the Pharisees were trying to warn Jesus of Herod because Herod was the one that had John the Baptist beheaded. During the conversation, the Pharisees told Jesus that Herod would kill Him. Jesus kept His composure, He was fearless. Therefore He replied "Go Tell That Fox." He was not at all worried about it, He had foreknowledge of His crucifixion. I wonder how we would react if we were threatened.
Jesus knew that He had some more curing and healing to do. Therefore He did not need to dwell on the negative, but on the positive. Yes! He was well aware of the fact that He was going to be crucified but before He reached the cross He wanted to cross out the devil. Jesus wanted to deliver as many people as possible from the disease of sin. Therefore, He said "I DO CURE."
