'Half' in the Bible

For Tyre built herself an [impregnable] stronghold [on an island offshore],And she has heaped up silver like dustAnd gold like the mire of the streets.

For I will gather all nations against Jerusalem to battle, and the city will be captured and the houses plundered and the women ravished; and half of the city will be exiled, but the rest of the people will not be cut off from the city.

In that day His feet shall stand on the Mount of Olives, which lies before Jerusalem on the east; and the Mount of Olives will be split in half from the east to the west by a very large valley, and half of the mountain will move toward the north and half of it toward the south.

And in that day living waters will flow out from Jerusalem, half of them to the eastern sea (Dead Sea) and half of them to the western sea (the Mediterranean); it will be in summer as well as in winter.
