Mark 8:13

And He left them, and, entering into the ship, again departed to the other side.

After the miracle of the feeding Jesus lost no time in further teaching and healing at this place. Without delay He entered the boat with His disciples and crossed the Sea of Galilee into the region of Dalmanutha, in the district of Magdala, Matthew 15:39. This was a fertile district adjoining that of Gennesaret, and for that reason settled very thickly. Jesus always returned to Galilee for short trips, but the day of mercy for the Galileans had practically come to a close. His ancient enemies had not returned to Jerusalem, to all appearances. For no sooner had He begun the work of His ministry than they came out, probably from Capernaum. They here deliberately began a dispute, they tried to force the issue, they tempted Him. Their object was to get Him to do or say something that could be readily construed as being at variance with the Law of Moses. They hoped to gain their purpose in this case by having Him show a sign from heaven, a sign establishing His claim as the Messiah sent by God. They were not sincere in their urgent demand; they had no intention of believing on Him. If He had fulfilled their request, they would simply have denounced Him before the people as a false Messiah, in spite of all. The wickedness and hypocrisy of the question affected the Lord very deeply. He fetched a deep sigh in His spirit. He realized that the crisis had come, that henceforth there would be enmity to death against Him on the part of these members of the leading party in the Jewish Church. Then He said the solemn words, in the form of an oath: What sign does this generation seek? Verily I say unto you, if a sign will be given to this generation! This is an Aramaic form of speaking, leaving the sentence unfinished, the alternative unspoken. It is the strongest form of refusal. In their sense Jesus here and always refused them a sign. If the many miracles that had been performed in the presence of multitudes numbering thousands had made no impression on them, neither would some manifestation out of the sky penetrate their callous hearts. One sign He indeed is reserving for them and for the whole world, Matthew 12:38, a sign so wonderful that they would never understand, much less accept and believe it His resurrection from the dead. Having given the Pharisees this answer, He left them, and again crossed to the other side of the sea. The obstinacy and hardness of heart which these enemies exhibited hurt Him deeply, and so He wanted to be alone for a while and gain strength for further labors and combats.
