17:1-7 This psalm is a prayer. Feigned prayers are fruitless; but if our hearts lead our prayers, God will meet them with his favour. The psalmist had been used to pray, so that it was not his distress and danger that now first brought him to his duty. And he was encouraged by his faith to expect God would notice his prayers. Constant resolution and watchfulness against sins of the tongue, will be a good evidence of our integrity. Aware of man's propensity to wicked works, and of his own peculiar temptations, David had made God's word his preservative from the paths of Satan, which lead to destruction. If we carefully avoid the paths of sin, it will be very lead to destruction. If we carefully avoid the paths of sin, it will be very comfortable in the reflection, when we are in trouble. Those that are, through grace, going in God's paths, should pray that their goings may be held up in those paths. David prays, Lord, still hold me up. Those who would proceed and persevere in the ways of God, must, by faith prayer, get daily fresh supplies of grace and strength from him. Show thy marvellous loving-kindness, distinguishing favours, not common mercies, but be gracious to me; do as thou usest to do to those who love thy name.

PSALM 17

Ps 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.
