'Five' in the Bible

Yet gleanings will be left in it like the shaking of an olive tree,Two or three olives on the topmost bough,Four or five on the branches of a fruitful tree,Declares the Lord, the God of Israel.

In that day five cities in the land of Egypt will be speaking the language of Canaan and swearing allegiance to the Lord of hosts; one will be called the City of Destruction.

One thousand will flee at the threat of one man;You will flee at the threat of five,Until you are left as a flag on a mountain topAnd as a signal on a hill.
