I wait for the Lord, my soul waits,
    and in his word I hope;
my soul waits for the Lord
    more than those who watch for the morning,
    more than those who watch for the morning.
                                                        Psalm 130.5,6

Arvo Part’s De Profundis - details on Wikipedia here.

Thisis a musical setting of Psalm 130 - the setting is Latin, the translation is

From the depths, I have cried out to you, O Lord;
Lord, hear my voice. Let your ears be attentive
to the voice of my supplication.
If you, Lord, were to mark iniquities, who, O Lord, shall stand?
For with you is forgiveness; and because of your law, I stood by you, Lord.
My soul has stood by his word.
My soul has hoped in the Lord.
From the morning watch, even until night, let Israel hope in the Lord.
For with the Lord there is mercy, and with him is plenteous redemption.
And he will redeem Israel from all his iniquities.
