For thou hast maintained my right and my cause. David uniformly ascribes his military successes, not to his own ability, or even to the valour of his soldiers, but to God's favour. God's favour, which is secured by the justice of his cause, gives him victory after victory.
Thou surest in the throne judging right. While the late battle raged, God sat upon his heavenly throne, administering justice, awarding defeat and death to the wrong-doers who had wantonly attacked his people, giving victory and glory and honour to those who stood on their defence against the aggressors.
