(Pro 6:12 KJV) A naughty person, a wicked man, walketh with a froward mouth.
The OT does not hesitate to call evil, evil. Here it defines the “naughty" (worthless NASB) (1100) “wicked” (205) man. It does so with no apology. We are so polite and afraid to offend that we cannot communicate. How many times have you heard people tell you that everyone has worth? I guess it is true but keep in mind that every piece of garbage has worth, too. It is just that the worth is so little that it can’t be measured. Keep in mind that the repeated message of Proverbs is that people become this way because of preference. This is a deliberate choice. There are options.
The KJV calls him a “naughty” man. This is a bit confusing since we use the word for children who get into mischief. I would think that the word comes from “naught.” This is an old English word meaning zero. So you can see that the meaning is the same: worthless.
A “froward" (false NASB) (6143) “mouth” (6310) is more than just simply lying. It can involve deceiving with partial truth or truth and will obviously not be understood. Truth is a requirement of God. The KJV word here, “froward”, is not a misprint. You will still find the word in modern dictionaries. It means not easily controlled, wilful, contrary. It means it in a very negative sense. Some people replace slick for truth. You may never be able to catch them or pin them down, but they have false mouths. Unfortunately we find them in the church. They are to be condemned and labeled as worthless and wicked.
