Psalm 72:11, "Yes, all kings shall fall down before him. All nations shall serve him," is a powerful statement about the universal reign and dominion of the king described in the psalm. Here's a breakdown of its meaning:

"Yes, all kings shall fall down before him..." This phrase indicates submission, homage, and worship. "Falling down" is an act of profound respect and recognition of a higher authority. It suggests that even the most powerful rulers and leaders of the world will acknowledge the king's superior position and power.

"...All nations shall serve him." This phrase expands the scope beyond individual rulers to encompass entire populations and cultures. It speaks to the idea that all people, regardless of their nationality or background, will be subject to the king's rule and will obey his commands. "Serve" implies a dedication of labor, resources, and loyalty.

Context and Interpretation:

To fully understand the verse, we need to consider the broader context of Psalm 72:

The Messianic Interpretation: Traditionally, Psalm 72 has been interpreted as a prophecy about the Messiah, Jesus Christ. In this view, the "king" is Jesus, and the verse refers to the eventual recognition of his sovereignty by all people and nations. The "falling down" represents worship and the "serving" represents obedience to his teachings and participation in his kingdom.

The Royal Ideal Interpretation: Some scholars believe that Psalm 72 was originally written to celebrate the reign of a righteous earthly king, possibly Solomon. In this interpretation, the verse expresses the hope that all the world's rulers and peoples would be brought under the just and peaceful rule of the Israelite king.

In summary, Psalm 72:11 expresses the belief that the king (whether understood as a historical figure or a Messianic figure) will have universal dominion, with all rulers and nations acknowledging his authority and submitting to his reign.
