'Clear' in the Bible

For behold this selfsame thing, that ye sorrowed after a godly sort, what carefulness it wrought in you, yea, what clearing of yourselves, yea, what indignation, yea, what fear, yea, what vehement desire, yea, what zeal, yea, what revenge! In all things ye have approved yourselves to be clear in this matter.

Having the glory of God: and her light was like unto a stone most precious, even like a jasper stone, clear as crystal;

And the building of the wall of it was of jasper: and the city was pure gold, like unto clear glass.

And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb.
