".........whatsoever things are true,
whatsoever things are honest,
whatsoever things are just,
whatsoever things are pure,
whatsoever things are lovely,
whatsoever things are of good report;
if there be any virtue, and it there be any praise, think on these things."
............Philippians 4: 8 KJV
