'Riding' in the Bible

I saw in the night, and, behold, a man riding upon a red horse, and he stood among the myrtle-trees that were in the bottom; and behind him there were horses, red, sorrel, and white.

Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy king cometh unto thee; he is just, and having salvation; lowly, and riding upon an ass, even upon a colt the foal of an ass.
