Why did Jesus kill the barren fig tree in the Bible Prophecy? Luke 13:6-9. Fig trees must bear fruit consistently, not seasonally. Jerusalem and the Jewish culture must bear (figs) fruit or face destruction, according to bible prophecy. Jesus prophesied, Matthew 23:31, "Oh Jerusalem , Jerusalem, the one who kills the prophets" .....Matthew 24:1, "not one stone shall be left here upon another." Biblical prophecy was fulfilled in 70 A.D., when Rome destroyed Jerusalem and Israel.
