'Perfect' in the Bible

But let endurance have its perfect work, that ye may be perfect and complete, lacking in nothing.

Every good gift and every perfect gift comes down from above, from the Father of lights, with whom is no variation nor shadow of turning.

But he that fixes his view on the perfect law, that of liberty, and abides in it, being not a forgetful hearer but a doer of the work, he shall be blessed in his doing.

For we all often offend. If any one offend not in word, he is a perfect man, able to bridle the whole body too.
