Jesus found a young donkey and sat on it, as it is written: ”Do not be afraid, Daughter Zion; see, your king is coming, seated on a donkey’s colt.” At first his disciples did not understand all this. Only after Jesus was glorified did they realize that these things had been written about him and that these things had been done to him.
These days, if visiting royalty were to come to town, or the President of the country, or even the Pope, they would be conveyed in a very nice limousine. They would also be accompanied by other people in more limousines. They might even have a police escort or other security around them.
Years before Jesus’ time, in the days of King David, people did something similar. When David’s son, Absalom, was plotting to take over the kingdom, he exalted himself by buying the fanciest chariot he could and then hiring fifty men to run ahead of him. (2 Samuel 15: 1)
Throughout time, the more important the person, the fancier the car, and the more people they have attending them.
