I saw heaven opened, and behold, a white horse, and he who sat on it is called Faithful and True. In righteousness he judges and makes war. His eyes are a flame of fire, and on his head are many crowns. He has names written and a name written which no one knows but he himself. He is clothed in a garment sprinkled with blood. His name is called “The Word of God.” The armies which are in heaven, clothed in white, pure, fine linen, followed him on white horses. Out of his mouth proceeds a sharp, double-edged sword that with it he should strike the nations. He will rule them with an iron rod. He treads the wine press of the fierceness of the wrath of God, the Almighty. He has on his garment and on his thigh a name written, “KING OF KINGS AND LORD OF LORDS.”
I will tell of the decree: The LORD said to me, “You are my son. Today I have become your father. Ask of me, and I will give the nations for your inheritance, the uttermost parts of the earth for your possession. You shall break them with a rod of iron. You shall dash them in pieces like a potter’s vessel.” Now therefore be wise, you kings. Be instructed, you judges of the earth. Serve the LORD with fear, and rejoice with trembling. Give sincere homage to the Son, lest he be angry, and you perish on the way, for his wrath will soon be kindled. Blessed are all those who take refuge in him.
