'Half' in the Bible

For I will gather all nations against Jerusalem to battle; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity, and the residue of the people shall not be cut off from the city.

And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east; and the mount of Olives shall be cleft in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.

And it shall come to pass in that day, that living waters shall go out from Jerusalem; half of them toward the eastern sea, and half of them toward the western sea: in summer and in winter shall it be.
