I have set thee for a strong trier among my people: and thou shalt know, and prove their way. 28All these princes go out of the way, they walk deceitfully, they are brass and iron: they are all corrupted. 29The bellows have failed, the lead is consumed in the fire, the founder hath melted in vain: for their wicked deeds are not consumed. 30Call them reprobate silver, for the Lord hath rejected them.
