The psalm prophecy is quoted by the apostle Peter in Acts 4:25-26 with this application of the effect of preaching Christ to the heathen world. The ruling with a rod of iron referred to the inexorable character of the law of Christ--the invincible word of God. The treading of the winepress of the fierceness and wrath of God was the symbol of the execution of the inflexible judgment of retribution. And in Revelation it was Almighty God, the supreme Judge of all men, who should formulate the sentence and render the judgment against the heathen nations.
