Paul Boyd

Notice he doesn't say I will give thanks to the Lord for my righteousness. No, this is a picture here of David's faith and trust not in himself, not in a plan to get back at the wicked, not to sue, but God. And it's also a picture here of his faith in the one to come, the righteous one, the one who was innocent, who was wrongly judged, who took David's sin and gave David his righteousness, the David to come, the perfect king, the atoning sacrifice—Jesus.
