'Five' in the Bible

and five of you shall chase a hundred, and a hundred of you shall put ten thousand to flight; and your enemies shall fall beside you by the sword.

And if it be from five years old even unto twenty years old, thy valuation of the male shall be twenty shekels, and for the female ten shekels.

And if it be from a month old even unto five years old, thy valuation of the male shall be five shekels of silver; and for the female thy valuation shall be three shekels of silver.
