51:1-2 Plea for mercy

51:3-6 David confronts how horrible his sins are

51:7-9 He pleas for complete forgiveness

51:10-12 Create in me a clean heart

51:13-17 God wants a whole hearted repentance

51:18-19 He asks God build Zion

The things David requests: God's mercy, blotting out of sins, washing, cleansing, created anew all find their greatest fulfillment in Jesus
