(Proverbs 19:28 KJV) An ungodly witness scorneth judgment: and the mouth of the wicked devoureth iniquity.
Here is another synonym for a liar, he is a “ungodly” (1100) “witness” (5707). The NASB has “rascally.” Neither gets to the root meaning of the word. The usual NASB translation comes closest. It is usually “worthless.” In the KJV it is usually translated as some variation of “children of Belial,” which is more literal and colorful.
However you want to translate it, the meaning is clear. Honesty and truth are a part of the default behavior of the righteous and as you have heard me say many time, God expects us to be righteous. That is one of the things that the Holy Spirit is sent to empower us toward.
So? Make this a day devoid of rascality. That is actually a word, by the way. At least my spell checker says so. Be a child of God, not a child of Belial.
