'Perfection' in the Bible

Is not thy reverence thy confidence? Thy hope -- the perfection of thy ways?

Canst thou by searching find out God? canst thou find out the Almighty unto perfection?

He shall not be rich, neither shall his substance continue, neither shall he prolong the perfection thereof upon the earth.

He setteth an end to darkness, and searcheth out all perfection: the stones of darkness, and the shadow of death.
