'Clear' in the Bible

You must abstain from things sacrificed to idols, from blood, from things strangled, and from fornication. Keep yourselves clear of these things, and it will be well with you. Farewell."

Then Paul, fixing a steady gaze on the Sanhedrin, said, "Brethren, it is with a perfectly clear conscience that I have discharged my duties before God up to this day."

This too is my own earnest endeavour--always to have a clear conscience in relation to God and man.
