David dares to ask God to act justly and drag off his hypocritical enemies. But for himself, he pleas for mercy. When God grants him victory over his enemies, he praises God who has heard his pleas for mercy. Then he asks the LORD to turn that same favor toward his people, and to save and bless them, be their shepherd and carry them forever (8-9). These are not the words of a braggart, who thinks he deserves blessing. They are the words of a man who knows who God is, and understands grace.
LORD, give us your mercy, for your name’s sake.
