Why Does Mashiach (Messiah) Arrive on a Donkey?

The ultimate Moshiach, he will be roichev al chamor. Moshiach will yet again be riding on the slow donkey. Why? 21st century, put Moshiach on a Mustang or Corvette. Let him get a cell already. A donkey tarries. A donkey delays us. Why a donkey? Because there may be a Jew who's not ready, who's not fit yet. There's a Jew who's on the fence. There's a Jew who's struggling. He's got to choose kedusha versus tumah, holiness versus contamination. He's got to choose ruchniyus versus gashmiyus, spirituality versus physicality. Roichev al chamor, you know what it means? Chamor means from the word chomer, physicality, gashmiyus, pleasure. Roichev means that there's a person out there who's going to choose to subjugate, to vanquish, to conquer the choice of physicality and say, "I want kedusha. I want purity. I want holiness. Yes, I'm challenged. Yes, I'm tempted, but I'm going to make the right choice. I'm going to be roichev al chamor." And that's why Moshiach is on a donkey, because it could be there ought to be one person. And just as Moshiach is about to come, he's going to forsake that person. That person is to be left behind? But the donkey goes slow, and that person has one last chance to choose kedusha, to choose holiness. And then Moshiach will capture him and bring him for the ride.
