Our practice this year has been to read the Psalms, which contain 5 books, book by book. Now we return to Book IV. Unlike some of the other books which make up the Psalter, the psalms in this book are mostly unassigned to a particular author.

You will find an introduction to the Psalms, here.

Here is a prayer from Gregory of Nazianus (329-389) who was an early Church father.

Lord, as I read the psalms let me hear you singing. As I read your words, let me hear you speaking. As I reflect on each page, let me see your image. And as I seek to put your precepts into practice, let my heart be filled with joy. Amen.
Psalm 94  A community lament:  A better translation of “vengeance” would be “vindication” or “rectify the wrongs”. This psalm has a chiastic structure
  Introduction/Petition v 1-2
         complaint v 3-7
             questions 8-10
                    God’s care for the persecuted  v11-15
             questions 16-21
       confidence 22-23
Psalm 95 A hymn celebrating God as enthroned king.  Sing v 1-5, bow down v 6-7c, obey 7d-11.  What metaphors are used in this psalm?  Notice the change of speaker beginning  in verse 7d.    On Meribah and Massah see Ex 17:1-7 and Num 21:1-9.
Psalm 96 A hymn celebrating God’s kingship. Verses 1-3 summons to worship. Verses 4-6 God is the powerful creator. Verses 7-13 all nations and the universe is to praise God.
Psalm 97 A hymn celebrating God’s rule. Notice the use of storm and fire to describe God’s presence. Notice the repetition of justice.righteousness and their association with God.
