'Perfectly' in the Bible

If a man receives circumcision on the Sabbath so that the Law of Moses may not be broken, are you angry with me because I made a man perfectly well on the Sabbath?

You do not know Him, but I know Him perfectly; and were I to deny my knowledge of Him, I should resemble you, and be a liar. On the contrary I do know Him, and I obey His commands.

I have glorified Thee on earth, having done perfectly the work which by Thine appointment has been mine to do.

and on their behalf I consecrate myself, in order that they may become perfectly consecrated in truth.

I in them and You in Me, that they may be perfected and completed into one, so that the world may know [without any doubt] that You sent Me, and [that You] have loved them, just as You have loved Me.
