Out of the Depths (vocabulary note)

from NOTES on Psalm 130 (Jewish Study Bible, Marc Zvi Brettler, Adele Berlin) - Oxford University Press, 2004):
The main part of Psalm 130 is a personal petition (verses 1 - 6); this is followed by address to the wider community (verses 7 - 8), which builds upon this petition, explaining why it is good to petition God.  It is thus possible that an editor, the author of verses 7 - 8, has taken up and expanded an older psalm.  "Depths," elsewhere in Psalms only in Psalm 69:3 and 15 perhaps here a reference to the underworld, of being in a state near death (see Book of the Prophet Jonah 2:3 - 7). . .Sinners of their descendants normally need to be punished (see Exodus 34:7), but here God redeems, that is forgives, so no one is punished.  As in many psalms, the personal becomes the communal."
