This royal psalm concludes Book Two, with Psalm 72:18–20 serving as an epilogue for the entire book. The psalmist considers the future of David's royal line and Zion (see Psalms 46, 48). He prays that Israel's kings will be good and successful, spreading the Lord's blessing to all people worldwide. The exceptional righteousness and rule desired in this prayer hint at the future arrival of Jesus, the Son of David.
