David
Psalm 7:1ESV·traditional attribution

O LORD my God, in you do I take refuge; save me from all my pursuers and deliver me,

John Calvin Reformed @genevareformer

PSALM 7 David, loaded with unjust calumny, calls upon God to be his advocate and defender, and commits his innocence to the Divine protection. In the first place, he protests that his conscience did notaccuse him of the wickedness laid to his charge. Secondly, he shows how greatly it concerns the glory of God that he should execute judgment against the ungodly.

David appears before God to plead with him against the Accuser, who had charged him with treason and treachery. The case is here opened with an avowal of confidence in God. Whatever may be the emergency of our condition we shall never find it amiss to retain our reliance upon our God.

Matthew Henry Presbyterian @wholebiblehenry

Shiggaion is a song or psalm (the word is used so only here and Hab 3:1) - a wandering song (so some), the matter and composition of the several parts being different, but artificially put together - a charming song (so others), very delightful.
