Opening prayer

Blessed are you, Holy God, for in Jesus Christ you came to rule in our lives, not as a king, but as a humble servant, riding on a donkey. Enter into our hearts this day with your glory, that we may greet you with shouts of praise; through Christ, our Sovereign and Savior. (Prestbyterian Church)

Reading

Zechariah 9:9-13

9 Rejoice greatly, Daughter Zion! Shout, Daughter Jerusalem! See, your king comes to you, righteous and victorious, lowly and riding on a donkey, on a colt, the foal of a donkey. 
10 I will take away the chariots from Ephraim and the warhorses from Jerusalem, and the battle bow will be broken. He will proclaim peace to the nations. His rule will extend from sea to sea and from the River to the ends of the earth. 
11 As for you, because of the blood of my covenant with you, I will free your prisoners from the waterless pit. 
12 Return to your fortress, you prisoners of hope; even now I announce that I will restore twice as much to you. 
13 I will bend Judah as I bend my bow and fill it with Ephraim. I will rouse your sons, Zion, against your sons, Greece, and make you like a warrior’s sword.
Psalm 118:24-29

24The Lord has done it this very day;
    let us rejoice today and be glad.

25 Lord, save us!
    Lord, grant us success!

26 Blessed is he who comes in the name of the Lord.
    From the house of the Lord we bless you.[a]
27 The Lord is God,
    and he has made his light shine on us.
With boughs in hand, join in the festal procession
    up[b] to the horns of the altar.

28 You are my God, and I will praise you;
    you are my God, and I will exalt you.

29 Give thanks to the Lord, for he is good;
    his love endures forever.
