Psalm 42

We sang this today at Mass:

As the deer longs for flowing streams,

so longs my soul for You, O God.

My soul does thirst for the living God;

when shall I come to see Your face?

My tears have fed me day and night

while some have said, "Where is your God?"

But I recall, as my soul pours dry,

the days of praise within Your house.

Why do I mourn and toil within

when it is mine to hope in God?

I shall again sing praise to Him;

He is my help - He is my God.

and this is the best version I found, if you want to hear the melody.
