'Mounted' in the Bible

"I stared into the night, and there was a man mounted on a red horse! The horse was standing among the myrtle trees in a ravine. Behind him there were red, brown, and white horses."

Rejoice greatly, O daughter of Zion!Shout in triumph, O daughter of Jerusalem!Behold, your king is coming to you;He is just and endowed with salvation,Humble, and mounted on a donkey,Even on a colt, the foal of a donkey.
