'Perfectly' in the Bible

He *said to them, “Why are you afraid, you men of little faith?” Then He got up and rebuked the winds and the sea, and it became perfectly calm.

And He got up and rebuked the wind and said to the sea, “Hush, be still.” And the wind died down and it became perfectly calm.

Paul, looking intently at the Council, said, “Brethren, I have lived my life with a perfectly good conscience before God up to this day.”
