Ps 129:1-2
From the depths I have cried out to Thee, O Lord: Lord, hear my prayer: from the depths I have cried out to Thee, O Lord.
Haydock
Ver. 1: Canticle. David might compose it after his sin, though it might suit the captives, and all sinners, as well as the souls in purgatory. (Berthier) — It has long been recited in their behalf. (Worthington) — Depths of the prison of expiation, or from this vale of misery, (Berthier) captivity, (Calmet) and from the bottom of my heart. (St. Chrysostom)
