John 12:12-15 (NIV)
The next day the great crowd that had come for the festival heard that Jesus was on his way to Jerusalem. They took palm branches and went out to meet him, shouting, “Hosanna!” “Blessed is he who comes in the name of the Lord!” “Blessed is the king of Israel!” 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.”

Revelations 19:11-14 (NIV)
I saw heaven standing open and there before me was a white horse, whose rider is called Faithful and True. With justice he judges and wages war. His eyes are like blazing fire, and on his head are many crowns. He has a name written on him that no one knows but he himself. He is dressed in a robe dipped in blood, and his name is the Word of God. The armies of heaven were following him, riding on white horses and dressed in fine linen, white and clean.

Revelations 11:15 (NIV)
The seventh angel sounded his trumpet, and there were loud voices in heaven, which said: “The kingdom of the world has become the kingdom of our Lord and of his Messiah, and he will reign for ever and ever.”
