Ellicott's Commentary On The Whole Bible
Psalms 67 - Introduction
LXVII.
This is a noble hymn of praise, which for its fine and free expression of grateful dependence on the Divine grace was worthy to become, as it has become, a Church hymn for all time. The last two verses connect the hymn immediately with harvest, and it would look as if this allusion had actually been added for some special occasion to what was a general song of praise, since the refrain in Psalms 67:5, besides marking its choral arrangement, indicates what appears to be the proper ending of the psalm.
