The answer is: A prophecy of the future kingdom after the return of Christ

Psalm 72 - Often viewed as a messianic psalm, it describes the ideal reign of a righteous king whose rule brings justice and peace. This vision aligns with prophecies in Isaiah (Isaiah 9:6-7) about the coming Messiah, emphasizing God's ultimate plan for restoration and unity through Christ.

Psalm 72 portrays the picture of a king whose reign is marked by justice, righteousness, and peace—a vision that many see as more than just poetic fancy. It resonates with the deep aspirations found not only in Jewish tradition but also in the broader human quest for a ruler who embodies fairness. This psalm is centered on qualities that seem timeless: enduring love, the welfare of the oppressed, and an inclination toward the rich blossoms of life—turning ecological tragedy into abundance.

Delving deeper, you might recall that Solomon—often understood as the author—was meant to be a symbol of such wisdom. His story emphasizes not just a king's exterior victory but hints at internal character—a king both in title and in righteous heart. It’s fascinating to note how Psalm 72 echoes themes of later prophets, like Micah—even mentioning "beat swords into plowshares," embodying nations coming together under a shared banner.

Historians and theologians highlight commonplace events of ancient rulership that influence the interpretation of royal psalms, even within various cultures surrounding ancient Israel. For instance, when rulers like Hammurabi or Cyrus of Persia are studied, we see social reform as a marker of leadership. Psalm 72’s aspirations align songfully with these ancient leadership ideals, illustrating a universal desire for equity and benevolent rule, all of which point towards a world many hope to see in our human journey!
