Sunday is what we commonly call Palm Sunday. It commemorates Jesus’ triumphal entry into Jerusalem before Passover, just a few days before His death and glorious resurrection.
The next day a great multitude that had come to the feast, when they heard that Jesus was coming to Jerusalem, took branches of palm trees and went out to meet Him, and cried out: “Hosanna! ‘Blessed is He who comes in the name of the Lord !’ The King of Israel!” Then Jesus, when He had found a young donkey, sat on it; as it is written: “Fear not, daughter of Zion; Behold, your King is coming, Sitting on a donkey’s colt.” His disciples did not understand these things at first; but when Jesus was glorified, then they remembered that these things were written about Him and that they had done these things to Him.
John 12:12-16 NKJV

Upon Jesus’ resurrection and ascension, the disciples remembered the prophecies concerning these things:

The above is just one fulfilled prophecy surrounding His first coming. We can be sure future prophecies will be fulfilled just as well.
The next time Jesus arrives in Jerusalem, it will not be upon a donkey and He will no longer present Himself as the perfect sacrificial Lamb. Let’s look again at the book of Zechariah:


The book of Revelation has something to say about the next time Jesus arrives in Jerusalem, too:

The next time Jesus arrives in Jerusalem, it will be as the Lion of Judah: the King of kings and Lord of lords.
To Him be all glory, honor, power and praise forever and ever!
Maranatha!
