As Revelation points out, Jerusalem was the location of the death of the Messiah. John highlights that for a reason in his prophecy of the end time. Jesus was killed, in part, because He testified that Judaism's works were evil, and because its traditions kept God's people from recognizing and accepting God in the flesh. It won't be until God intervenes that the House of Judah will mourn for the One whom they pierced (Zechariah 12:10).
