'Horseman' in the Bible

So a horseman went to meet Jehu and said, “This is what the king asks: ‘Do you come in peace?’”Jehu replied, “What do you have to do with peace? Fall in behind me.”The watchman reported, “The messenger reached them but hasn’t started back.”

So he sent out a second horseman, who went to them and said, “This is what the king asks: ‘Do you come in peace?’”Jehu answered, “What do you have to do with peace? Fall in behind me.”
