(Proverbs 15:28 KJV) The heart of the righteous studieth to answer: but the mouth of the wicked poureth out evil things.
The conversations of the “righteous” (6662) are different from those of the “wicked” (7563). Some would seem obvious such as the choice of vocabulary. Godly people tend to refrain from vulgarities and obscenity. Truth is also required of those who walk upright. Courtesy is expected.
Here is says we should be slow to speak. The believer “studieth” (ponders NASB) (1897) before opening the mouth. There are a variety of translations but they all deal with struggling with the ideas and ways of expressing them before you open your mouth.
So? Be the last one to comment instead of the first. That will give not only a chance to hear what others say but think about our words. In writing this blog I rewrite and edit at least twice before it is posted. Even then I later find spelling and grammar errors. I probably never would see my mistakes in facts.
