The KJV is based on far later and even more corrupt texts than modern versions. But even the best ones in the original languages are copies of copies of copies of copies of copies of copies of copies of copies of copies and are full of alterations and insertions by scribes, sometimes very lengthy sections that often preach evil (Jeremiah 8:8).

People usually cling too tightly to their texts, like the Pharisees, when they're being self-righteous and like to condemn others and control them with burdens of rules and threats for breaking them. And that's definitely all that's coming from most pulpits today. They don't even care, they just love to brag to the world about how much better they are than everyone else for following all the rules outwardly while being full of greed and hatred and lust for power. The Pharisees often did not understand Jesus because they were so unwilling to break their traditions or go the slightest bit beyond their scripture down to the letter. He wanted them to have common sense and morals. They emphasized blindly following "the law" much like modern Christianity emphasizes following "what the Bible says", and thus could not see the obvious because they refused to be open to it.
