Ellicott's Commentary On The Whole Bible
Psalms 108 - Introduction
CVIII.
This psalm is taken with some variations from Psalms 57, 60, Psalms 108:1 being from Psalms 57:7; Psalms 108:6 being from Psalms 60:7, where see Notes.
The principal variations are in Psalms 108:3, Jehovah for Adonai.
In Psalms 108:6 the construction is changed to suit the new arrangement and the variation in Psalms 108:10, on which see Note, Psalms 60:8. For the authorship of the parts of which the psalm is composed, see their Introductions. The ascription of the composite production to David furnishes a strong presumption against the historical value of the inscriptions.
