Zechariah 14 is an interesting prophecy which gives some very specific earth related (speaking of the actual dirt and stone, mountains, valleys, rivers...) events that obviously haven't happened. Where do you place this prophecy in the history of the earth? Is Jerusalem a sea port? Will it become a sea port? Does the Jordon flow into the sea? Of course, I take the prophecy as having little allegorical meaning, but I thought that the BB folks might enjoy posting what their thoughts are about what I take is most specific and unusual prophecy of the Lord's return and the change it brings to the earth and people who survive.
