This composite psalm takes its first five verses from Psalm
57:7-11, and its remaining eight verses from Psalm 60:5-12.
The first part of Psalm 57 deals with the early experiences of
David described in 1 Samuel 24, but as for the last part (used in Psalm 108)
there is more uncertainty (Psalms Studies, Psa. 57) — it may have
been written at a later time, and appended to the first six verses of Psalm
Psalm 60 definitely deals with the critical experiences of
David’s reign described in 2 Samuel 8 (see notes there).
So, it seems probable that all of Psalm 108 deals with the
same period as Psalm 60 — Judah’s wars by which David extended and
consolidated his kingdom with victories over Edom, Moab, and Philistia
For details on this psalm, then, see the title and background
history on Psalm 60 (Vol. 1, pp. 336,337) and the commentary on the appropriate
verses in both Psalms 57 and 60.
