16. These are inveterate murmurers (grumblers) who complain [of their lot in life], going after their own desires [controlled by their passions]; their talk is boastful and arrogant, [and they claim to] admire men's persons and pay people flattering compliments to gain advantage.
17. But you must remember, beloved, the predictions which were made by the apostles (the special messengers) of our Lord Jesus Christ (the Messiah, the Anointed One).
18. They told you beforehand, In the last days (in the end time) there will be scoffers [who seek to gratify their own unholy desires], following after their own ungodly passions.
