I would like to find all the instances in the Greek text of Hebrews where πιστεύω or πίστις are used. I don't remember how to do it. The latest Logos help information doesn't contain any help and I can never seem to find out how to search for anything in the wiki. I miss my old Englishman's Greek Concordance. Can anyone show me the various ways I can accomplish this? Thanks ahead of time.
