The sixth Sunday of Lent is Palm Sunday. The Lord rides into Jerusalem. We will read the short version of this entry from Mark, but here is the longer one from Matthew:
When they had come near Jerusalem … Jesus sent two disciples, saying to them, “Go into the village ahead of you, and immediately you will find a donkey
The disciples brought the donkey and its foal… and put their cloaks on them, and he sat on them. A very large crowd spread their cloaks on the road, and others cut branches from the trees and spread them on the road. The crowds that went ahead of him and that followed were shouting, “Hosanna to the Son of David! Blessed is the one who comes in the name of the Lord!
Matthew points out that the Lord is now doing what Zechariah said he would:
Rejoice greatly, O daughter Zion! Shout aloud, O daughter Jerusalem! Lo, your king comes to you; triumphant and victorious is he, humble and riding on a donkey, on a colt, the foal of a donkey.
The Lord is at war, riding out to confront the malevolent forces arrayed against mankind. But this king is so confident in his victory that he does not ride a war horse but a much more peaceful animal.
