Ellicott's Commentary for English Readers
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 Psalm 67:5, besides marking its choral arrangement, indicates what appears to be the proper ending of the psalm.
Title.—See titles, Psalms 4, 66
To the chief Musician on Neginoth, A Psalm or Song. God be merciful unto us, and bless us; and cause his face to shine upon us; Selah.(1) This verse is an adaptation of the priestly benediction (Numbers 6:24-26).
Upon us.—Rather, with, or among us; a variation from the formal benediction.
That thy way may be known upon earth, thy saving health among all nations.(2) Saving health.—The Hebrew word is that generally rendered “salvation,” but often better rendered “help,” or “deliverance.” By “health” the translators meant “healing power,” as in Shakespeare, King John, Act V., Scene 2:—
“For the health and physick of our right.”
Let the people praise thee, O God; let all the people praise thee.(3)Praise.—Better, give thanks.
O let the nations be glad and sing for joy: for thou shalt judge the people righteously, and govern the nations upon earth. Selah.(4) For thou shalt judge:—Better, for thou judgest.
And govern. . . .—Better, and dost lead. The word is used in Psalm 23:3 of the “pastoral” care of God.
Then shall the earth yield her increase; and God, even our own God, shall bless us.(6) Then shall the earth yield her increase.—It seems more in keeping with the expression of thanks to render here with the LXX. and Vulg., “The land hath yielded her increase.”
