Psalm 129 is one of the Psalms of Ascent, likely recited on pilgrimages to Jerusalem. So I invite you to read it alongside this Pilgrim's Prayer by Thomas Merton:
My Lord God, I have no idea where I am going.
I do not see the road ahead of me.
I cannot know for certain where it will end.
Nor do I really know myself,
and the fact that I think that I am following your will
does not mean that I am actually doing so.
But I believe that the desire to please you does in fact please you.
And I hope I have that desire in all that I am doing.
I hope that I will never do anything apart from that desire.
And I know that if I do this you will lead me by the right road, though I may know nothing about it.
Therefore will I trust you always, though I may seem to be lost and in the shadow of death.
I will not fear,
for you are ever with me,
and you will never leave me to face my perils alone.
When was a time when you had trouble seeing the road ahead of you?
1 “Often have they attacked me from my youth” —let Israel now say—
2 “often have they attacked me from my youth, yet they have not prevailed against me.
3 The plowers plowed on my back; they made their furrows long.”
4 The Lord is righteous; he has cut the cords of the wicked.
5 May all who hate Zion be put to shame and turned backward.
6 Let them be like the grass on the housetops that withers before it grows up,
7 with which reapers do not fill their hands or binders of sheaves their arms,
8 while those who pass by do not say, “The blessing of the Lord be upon you! We bless you in the name of the Lord!”
