Ps 8:1-9. Upon [or according to the] Gittith, probably means that the musical performance was directed to be according to a tune of that name; which, derived from Gath, a "wine-press," denotes a tune (used in connection with gathering the vintage) of a joyous character. All the Psalms to which this term is prefixed [Ps 8:1; 81:1; 84:1] are of such a character. The Psalmist gives vent to his admiration of God's manifested perfections, by celebrating His condescending and beneficent providence to man as evinced by the position of the race, as originally created and assigned a dominion over the works of His hands.

      1. thy name--perfections (Ps 5:11; 7:17).
      who hast set--literally, "which set Thou Thy glory," &c., or "which glory of Thine set Thou," &c., that is, make it more conspicuous as if earth were too small a theater for its display. A similar exposition suits the usual rendering.
