'Half' in the Bible

For I will gather all the nations against Jerusalem to wage war; the city will be taken, its houses plundered, and the women raped. Then half of the city will go into exile, but the remainder of the people will not be taken away.

On that day his feet will stand on the Mount of Olives which lies to the east of Jerusalem, and the Mount of Olives will be split in half from east to west, leaving a great valley. Half the mountain will move northward and the other half southward.

Moreover, on that day living waters will flow out from Jerusalem, half of them to the eastern sea and half of them to the western sea; it will happen both in summer and in winter.
