'Perfected' in the Bible

After He was perfected, He became the source of eternal salvation for all who obey Him,

(for the law perfected nothing), but a better hope is introduced, through which we draw near to God.

For the law appoints as high priests men who are weak, but the promise of the oath, which came after the law, appoints a Son, who has been perfected forever.

For by one offering he hath perfected for ever them that are sanctified.

since God had planned something better for us, so that they would not be perfected without us.
