Luther on Psalm 130

"Luther being once asked which were the best Psalms, replied, Psalmi Paulini;and when his companions at table pressed him to say which these were, he answered: Psalms 32:1-11; Psalms 51:1-19; Psalms 130:1-8; Psalms 143:1-12."
Franz Delitzsch

Out of the depths have I cried unto Thee, O LORD.
Lord, hear my voice: 

let Thine ears be attentive to the voice of my supplications.
If Thou, LORD, shouldest mark iniquities, 

O Lord, who shall stand?
But there is forgiveness with Thee, 

that Thou mayest be feared.
I wait for the LORD, my soul doth wait, 

and in His word do I hope.
My soul waiteth for the Lord more than they that watch for the morning: I say, more than they that watch for the morning.
Let Israel hope in the LORD: for with the LORD there is mercy, and with Him is plenteous redemption.
And He shall redeem Israel from all His iniquities.
Psalm 130
