'Rider' in the Bible

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.
