Psalm 130, known as the "De profundis," is historically connected to praying for the souls of the dead.
Among the many traditions of the Catholic Church is praying the De profundis for the faithful departed. This title is taken from the first two words of Psalm 130 in Latin, which begins “Out of the depths I have cried unto Thee, O Lord” (De profundis clamavi ad te, Domine).
It is one of the shortest Psalms and reflects the cry of an individual for God’s mercy. In 1736 Pope Clement XII encouraged Catholics to pray this Psalm for the dead, even making it a part of a person’s daily schedule. He wrote that it should be prayed while kneeling during the evening hours when the local church bell would sound, signaling everyone to stop what they were doing to pray.
Added to the Psalm is the short prayer “Eternal Rest grant unto them, O Lord,” one of the most common prayers of the Catholic Church for the deceased.
