“and a vessel comes out for the refiner.” This proverb is stretching the facts to make a point. Of course, when you remove the dross from silver, “a vessel” does not come out. Instead the silver is now ready for the silversmith. But the proverb is making the point that once the impurity is removed from the silver, the “vessel” almost appears on its own, automatically and quickly. That same thing is true of kingdoms, as the last part of the proverb says: “remove the wicked person from the presence of the king, and his throne will be established in righteousness” (Prov. 25:5). If the wicked people are removed from the presence of the king, then his throne will be established quickly; almost automatically.
This proverb has a wide application, because wicked people stop great things from happening in all organizations; in government, business, the Church, education, and more. Wicked people are prideful and selfish, and will not “go away” on their own. They have to be dealt with (Prov. 20:26).
