Ellicott's Commentary On The Whole Bible
Psalms 28 - Introduction
XXVIII.
This psalm gives no distinct indication of its authorship or date of composition. The writer appears to be in a critical condition of health (Psalms 28:1), and fears death as a mark of Divine punishment, involving him, though innocent, with the wicked. If the psalm is the product of one pen and time, and is really the expression of individual feeling, the writer was a king (Psalms 28:8). But the last two verses seem, both in rhythm and tone, to be from another hand, and to be the expression of national, not individual, confidence and hope. In the first seven verses the parallelism is hardly marked at all.
