Jamieson, Fausset and Brown on Psalms 17:2

PSALM 17

Psa 17:1-15. This Psalm is termed a prayer because the language of petition is predominant. With a just cause, sincerely presented, the writer prays for a just decision and help and protection. Pleading former mercies as a ground of hope, he urges his prayer in view of the malice, pride, rapacity, and selfishness of his foes, whose character is contrasted with his pious devotion and delight in God's favor.

2. sentence--acquitting judgment.

from thy presence--Thy tribunal.

things that are equal--just and right, do Thou regard.
