Rashi
the gittith A musical instrument that came from Gath, where craftsmen were found to make it (Machbereth Menachem p. 60). But our Sages said (Mid. Ps. 8:1): Concerning a nation [Edom] that is destined to be trodden like a winepress, as it is written (in Isaiah 63:3): “A winepress I trod alone.” However, the contents of the psalm do not indicate it.
Radak
For the Chief Musician: set to the Gittith. A Psalm of David. – We have expounded already above (Ps. 4:1) that Gittith is a kind of music. And there are those who say that David composed and recited (the Psalm) when he was in Gath; while others say (Ibn Ezra) that he gave it to the sons of Obed Edom the Gittite. This Psalm also is a hymn and rendering of praise and thanks to God, and a recounting of His acts of power.
