The tenth day of Nisan has just ended, four days before Passover, which is the day on which the Torah commanded every household to select a lamb to be sacrificed four days later on Passover. It’s also the day that Yeshua entered Jerusalem during his last Passover, riding on a donkey to fulfill the words of Zechariah the prophet: “Tell the daughter of Zion, ‘Behold, your King is coming to you, lowly, and sitting on a donkey, a colt, the foal of a donkey.’”
Yeshua was making it clear what king he was. It’s often said that the Jews of his day rejected this kind of king, but there’s a crowd of Jews welcoming him on the 10th of Nisan:
And a very great crowd spread their clothes on the road; others cut down branches from the trees and spread them on the road. Then the crowds who went before and those who followed cried out, saying: “Hosanna to the Son of David! ‘Blessed is he who comes in the name of the LORD!’ Hosanna in the highest!”
And when he had come into Jerusalem, all the city was moved, saying, “Who is this?”
So the crowds said, “This is Yeshua, the prophet from Nazareth of Galilee.” (Matt. 21:8-11)
Matthew uses the word crowd(s) three times in this brief passage, and it will appear again later.
