“Take away the dross from silver, and it will go to the silversmith for jewelry. Take away the wicked from before the king, and his throne will be established in righteousness.” Proverbs 25:4-5 (NKJV)
Too many times Presidents and kings appoint wicked men and/or women to places of power, and it is to their own detriment, and end destruction.
Just like kings of nations though, homes are in need of putting away the wicked in order that righteousness may be established. The head of the household needs to begin by searching the heart of self, and putting that wickedness away as an example to all in the home.
Kings and Presidents also need to look within themselves, then within their cabinet of leaders, and determine where there is wickedness then to cut it out, and cast it from them; then their rule will we established in righteousness.
