'Horseman' in the Bible

And the watchman stood on the tower in Jizreel, and saw Jehu's company as he came, and said, I see a company. And Joram said, Take a horseman, and send to meet them, and let him say, Is it peace?

The horseman springing up, and the glitter of the sword, and the flash of the spear, and a multitude of slain, and a mass of carcases, and no end of corpses: they stumble over their corpses.
