Upon Muthlabben, or, after the manner according to "death to the Son," by which some song was known, to whose air or melody the musician is directed to perform this Psalm. This mode of denoting a song by some prominent word or words is still common (compare Psa 22:1). The Psalmist praises God for deliverance from his enemies and celebrates the divine government, for providing security to God's people and punishment to the wicked. Thus encouraging himself, he prays for new occasions to recount God's mercies, and confident of His continued judgment on the wicked and vindication of the oppressed, he implores a prompt and efficient manifestation of the divine sovereignty. (Psa. 9:1-20) Heartfelt gratitude will find utterance.
