'Rider' in the Bible

Then I looked, and there was a white horse! Its rider had a bow, and a victor's crown had been given to him. He went out as a conqueror to conquer.

A second horse went out. It was fiery red, and its rider was given permission to take peace away from the earth and to make people slaughter one another. So he was given a large sword.

When the lamb opened the third seal, I heard the third living creature say, "Go!" I looked, and there was a black horse! Its rider held a scale in his hand.

Then I saw heaven opened, and there was a white horse. Its rider is called Faithful and True, and He judges and makes war in righteousness.

Then I saw the beast, the kings of the earth, and their armies gathered together to wage war against the rider on the horse and against His army.

The rest were killed with the sword that came from the mouth of the rider on the horse, and all the birds were filled with their flesh.
