20 Then began he [Jesus] to upbraid the cities wherein most of his mighty works were done, because they repented not:
21 Woe unto thee, Chorazin! woe unto thee, Bethsaida! for if the mighty works, which were done in you, had been done in Tyre and Sidon, they would have repented long ago in sackcloth and ashes.
22 But I say unto you, It shall be more tolerable for Tyre and Sidon at the day of judgment, than for you.
23 And thou, Capernaum, which art exalted unto heaven, shalt be brought down to hell: for if the mighty works, which have been done in thee, had been done in Sodom, it would have remained until this day.
24 But I say unto you, That it shall be more tolerable for the land of Sodom in the day of judgment, than for thee.
25 At that time Jesus answered and said, I thank thee, O Father, Lord of heaven and earth, because thou hast hid these things from the wise and prudent, and hast revealed them unto babes.
26 Even so, Father: for so it seemed good in thy sight.

Josephus commented about these places indicating they were still known locations prior to his death in the early 100's AD. Sometime following, during that first thousand years of Christendom, Chorazin, Bethsaida and Capernaum ceased to remain. Since then, historians make educated guesses as to their locations and fates.
A city whose name appears only in the woe pronounced against it by Christ (Matthew 11:21; Luke 10:13). Its appearance there, however, shows that it must have been a place of some importance, and highly privileged by the ministry of Jesus. It was already deserted in the time of Eusebius, who places it 2 miles from Capernaum (Onom, s.v.). We can hardly doubt that it is represented by the extensive ruins of Kerazeh, on the heights to the north of Tell Chum. It is utterly desolate: a few carved stones being seen among the heaps. There are traces of a Roman road which connected the ancient city with the great highway between north and south which touched the lake shore at Khan Minyeh.

Although Jesus centered His ministry in Capernaum, the people of that city did not follow him. Jesus pronounced a curse on the city for its unbelief (Matthew 11:23-24), predicting its ruin (Luke 10:15). So strikingly did this prophecy come true that only recently has Tell Hum been identified confidently as ancient Capernaum.
