De Profundis (Ps. cxxix)
Out of the depths I have cried to thee, O Lord: Lord, hear my voice. Let thy ears be attentive to the voice of my supplication. If thou, O Lord, wilt mark iniquities: Lord, who shall stand it. For with thee there is merciful forgiveness: and by reason of thy law, I have waited for thee, O Lord. My soul hath relied on his word: My soul hath hoped in the Lord. From the morning watch even until night, let Israel hope in the Lord. Because with the Lord there is mercy: and with him plentiful redemption. And he shall redeem Israel from all his iniquities.
Rest eternal grant unto them, O Lord, and let perpetual light shine upon them.
May they rest in peace. Amen.
