Jamieson, Fausset and Brown on Psalms 7:1-2

PSALM 7

Psa 7:1-17. Shiggaion--a plaintive song or elegy. Though obscure in details, this title seems to intimate that the occasion of this Psalm was some event in David's persecution by Saul. He prays for relief because he is innocent, and God will be glorified in his vindication. He thus passes to the celebration of God's righteous government, in defending the upright and punishing the wicked, whose malignant devices will result in their own ruin; and, confident of God's aid, he closes with rejoicing.

1-2. Though many enemies set upon him, one is singled out as prominent, and compared to a wild beast tearing his prey to pieces (compare 1Sa 20:1; 23:23; 26:19).
