'Half' in the Bible

So Hanun took David's servants, and after cutting off half the hair on their chins, and cutting off the skirts of their robes up to the middle, he sent them away.

But the people said, It is better for you not to go out: for if we are put to flight, they will not give a thought to us, and if death overtakes half of us, it will be nothing to them: but you are of more value than ten thousand of us: so it is better for you to be ready to come to our help from this town.

So the king went over to Gilgal, and Chimham went with him: and all the people of Judah, as well as half the people of Israel, took the king on his way.
