How come there were seven horsemen of the Apocalypse in the Bible?

and 12 disciples of Jesus?

and ten commandments?

It's real confusing.

maybe what it means since there's seven horsemen of the Apocalypse and six is the number for the human...7*6=42.

Maybe it means the horseman of the apocalypse and the human beings are going to be friends and the humans can get a ride on the back of the cool apocalypse horses.
