'Rider' in the Bible

Now the watchman was standing on the tower in Jezreel. He saw Jehu’s troops approaching and shouted, “I see troops!”Joram responded, “Choose a rider and send him to meet them and have him ask, ‘Do you come in peace?’”

and the rider on the horse goeth to meet him, and saith, 'Thus said the king, Is there peace?' and Jehu saith, 'What -- to thee and to peace? turn round behind me.' And the watchman declareth, saying, 'The messenger came unto them, and he hath not returned.'

And he sendeth a second rider on a horse, and he cometh in unto them, and saith, 'Thus said the king, Is there peace?' and Jehu saith, 'What -- to thee and to peace? turn round behind me.'
