I consider Psalm 5 to the centerpiece of a group of laments beginning in Psalm 3 and ending in Psalm 7. The superscripts for this set of psalms suggest an intentional composition strategy functioning to unify around the Davidic drama.
(3:1) A PSALM OF DAVID, WHEN HE FLED FROM ABSALOM HIS SON.
(4:1) TO THE CHOIRMASTER: WITH STRINGED INSTRUMENTS.
A PSALM OF DAVID.(5:1) TO THE CHOIRMASTER: FOR THE FLUTES.
A PSALM OF DAVID.(6:1) TO THE CHOIRMASTER: WITH STRINGED INSTRUMENTS; ACCORDING TO THE SHEMINITH.
A PSALM OF DAVID.
(7:1) A SHIGGAION OF DAVID, WHICH HE SANG TO THE LORD CONCERNING THE WORDS OF CUSH, A BENJAMINITE.
It appears to me that the superscripts of Psalm 3 & 7 bracket these laments with historical information concerning the life of David: Psalm 3 concerns David's fleeing from Absalom (2 Samuel 15); while Psalm 7 may refer to one or two later incidents: Shimei the Benjamite's curses against David (2 Samuel 16:1-23), and/or possibly the Cushite's news of Absalom's death (2 Samuel 18:31). Within this historical bracket (inclusio), Psalms 4-6 are connected with a chiasitic (A-B-A) pattern of instrumental directives to the "Choirmaster": strings - winds - strings.
Thus, Psalm 5 is the liturgical center for this set of laments anchored in the redemptive-historical situation where God's anointed king has been exiled from the throne and groans for final restoration.
Morning and Evening
Within this Davidic drama, I am impressed by a common theme surrounding morning and evening.
Upon closer examination of the word "morning" in the Psalms, I found that it is used most often to express confidence and hope that Yahweh will act in the morning to bring salvation, to deliver from the time of trouble. Conversely, evening/night is a metaphor for the time of trouble/distress, even from God's own wrath:
The "morning" is also used to express thanksgiving for Yahweh's faithful protection through the distress of the night:
Psalms 3-7 also seem to draw upon the theme of divine protection and divine deliverance by its use of morning and evening.
Resolution: New Creation in the Christ
"Morning" and "evening" are creation motifs. David's throne is not simply a throne for establishing justice in Israel, but for the entire cosmos. God had promised to set the entire world to right through a chosen seed, his annointed son. I think that is why David's psalms most often carry historical ambiguity. Not simply because the psalmists indend to express "timeless truths" or "an individual's existential struggles that relate to experiences of many", but because the Psalter is comprehensive and cosmic, concerned with the summation of all of history and creation with respect to God's promises through his chosen, annointed leadership--David's throne.
Thus, I read David's creation psalm (Psalm 8) as a praise arising from Yahweh's faithfulness to answer his laments of Psalms 3-7. David has been restored to the throne, "crowned with glory and honor"; peace and harmony has been restored to God's creation (cf. Gen 1 & 2). And this movement from lament to praise is a microcosm of the Psalter as a whole: God will answer the prayers of David to bring praise and worship to him in all creation.
David's greatest son, Jesus, has faced the full night of God's wrath but his tears of blood have turned to tears of joy in his resurrection and exaltation to God's right hand forever. The dawn of morning has come. God has been faithful to His promises to David. Praise God for the new creation He brought about for us in Christ!
