'Five' in the Bible

And five of you shall chase a hundred, and a hundred of you shall chase ten thousand; and your enemies shall fall before you by the sword.

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

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