'Half' in the Bible

I will gather all the nations against Jerusalem, to lay siege against it. The city will be captured, the houses will be ransacked, the women raped, and half of the city will go into exile, but the remaining people will not be cut off from the city.

His feet will stand in that day on the Mount of Olives, east of Jerusalem. Then the Mount of Olives will be split in two from east to west, forming a very large valley, with half of the mountain moving toward the north and half toward the south.

At that time, flowing waters will run perennially from Jerusalem, half toward the Dead Sea and half to the Mediterranean Sea.
