Luke 19:37-38
As he was now approaching the path down from the Mount of Olives, the whole multitude of the disciples began to praise God joyfully with a loud voice for all the deeds of power that they had seen, saying, "Blessed is the king who comes in the name of the Lord! Peace in heaven, and glory in the highest heaven!"

O God,
    you have given us a time for every matter under heaven,
            a time to weep and a time to laugh;
Grant us this day of rejoicing,
         forgetting the mourning in the days ahead,
So that on this day we proclaim your kingdom to come
                and praise you for your glory.
In the name of the one whose entry into Jerusalem
       we celebrate today,
                                                            Amen.
