Luke 13:32
And he said unto them, Go ye, and tell that fox, Behold, I cast out devils, and I do cures to day and to morrow, and the third day I shall be perfected. And he said unto them, Go ye, and tell that fox, Behold, I cast out devils, and I do cures to day and to morrow, and the third day I shall be perfected.
The saying was given as an answer to Pharisees who came to tell Jesus to get out and leave that place because Herod intended to kill Him. Their warning came after they had determined to get rid of Him because they were amazed by His warning about the strait gate, and it was an attempt to intimidate Him into departing. The “fox” He told them to go and tell was Herod himself.
In reply He declared that He keeps driving out demons and healing people through today and tomorrow, and reaches His goal and is perfected on the third day. He added that He must keep walking His appointed course through today and tomorrow and the day following, because a prophet cannot perish outside Jerusalem. So the saying means He would not be turned aside by threats but would finish His work on His set time while moving steadily toward certain death in Jerusalem. In that stand it exposes the spiritual blindness of the Jewish teachers, who closed their eyes and ears, refused life, and loaded upon themselves the vengeance that destroyed Jerusalem.
