It's Palm Sunday today. No appropriate TSE poem, so here's the psalm from the liturgy for year B (which I think we're in now).

Open for me the gates of righteousness; *
I will enter them;
I will offer thanks to the LORD.
"This is the gate of the LORD; *
he who is righteous may enter."
I will give thanks to you, for you answered me *
and have become my salvation.
The same stone which the builders rejected *
has become the chief cornerstone.
This is the LORD'S doing, *
and it is marvelous in our eyes.
On this day the LORD has acted; *
we will rejoice and be glad in it.
Hosannah, LORD, hosannah! *
LORD, send us now success.
Blessed is he who comes in the name of the Lord; *
we bless you from the house of the LORD.
God is the LORD; he has shined upon us; *
form a procession with branches up to the horns of the altar.
"You are my God, and I will thank you; *
you are my God, and I will exalt you."
Give thanks to the LORD, for he is good; *
his mercy endures for ever.
