as long as the sun shines
The sun is a symbol of constancy and endurance. In ancient Near Eastern cultures, the sun was often associated with divine presence and blessing. This phrase suggests the enduring nature of the king's reign, which is a foreshadowing of the eternal reign of Christ. The sun's daily rising and setting is a reminder of God's faithfulness, as seen in Lamentations 3:22-23, where His mercies are new every morning. The imagery here points to the everlasting nature of God's covenant with David, fulfilled in Jesus.

as long as the moon remains
The moon, like the sun, is a symbol of time and continuity. Its phases and cycles were used to mark time in ancient Israel. This phrase underscores the perpetual nature of the king's influence and the enduring legacy of his righteous rule. The moon's presence in the night sky serves as a reminder of God's promises, as seen in Psalm 89:37, where the moon is described as a faithful witness in the sky. This reflects the eternal nature of Christ's kingdom, which will not wane or diminish.

through all generations
This phrase highlights the lasting impact of the king's reign across time. It suggests a legacy that transcends individual lifetimes, pointing to the eternal kingdom of Christ. The promise of a kingdom that endures through all generations is rooted in the Davidic Covenant, as seen in 2 Samuel 7:16, where God promises David that his throne will be established forever. This is ultimately fulfilled in Jesus, whose kingdom is not limited by time or human succession. The continuity of God's promises through generations is a testament to His faithfulness and sovereignty.

"Cum sole et luna semper Aratus erit."

OVID: Amor., xv. 16.

The phrase "in the presence of the moon" (see the same expression, Psalm 72:17, and compare Job 8:16), means, not by the moonlight, but as long as the moon shines. (Comp. Psalm 72:7.) On the other hand, our phrase "under the moon" refers to space. With this passage Psalm 89:36-37, alone in Hebrew poetry exactly compares, or may perhaps have been borrowed from here. . . .
