'Half' in the Bible

For I will get all the nations together to make war against Jerusalem; and the town will be overcome, and the goods taken from the houses, and the women taken by force: and half the town will go away as prisoners, and the rest of the people will not be cut off from the town.

And in that day his feet will be on the Mount of Olives, which is opposite Jerusalem on the east, and the Mount of Olives will be parted in the middle to the east and to the west, forming a very great valley; and half the mountain will be moved to the north and half of it to the south.

And on that day living waters will go out from Jerusalem; half of them flowing to the sea on the east and half to the sea on the west: in summer and in winter it will be so.
