The dedication line says this was written by a Temple cantor, one of the Kohathites. Some scholars note that this psalm cannot be associated with any historical figure. Rather, it sounds like an idealized image of a royal wedding. Our only clue is that the writer of Hebrews quotes a bit (Hebrews 1:8-9) and says it is messianic. So the Jewish scholars had concluded, as well.
The underlying theme is that God has made all of this possible. The psalmist cites the awesome power of the vision that struck him, so he can’t help but write this hymn. He gave it his best artistry because one cannot take lightly the Anointed of God.
He describes a warrior king, wearing his fanciest armor. But make no mistake: This is the real stuff worn in battle. Anyone would be stirred at the sight. Indeed, “Nations fall at your feet.” His throne is eternal and His justice is the definition of justice for the whole universe. He is indeed the Anointed One. Could any palace house such a mighty One? His would be paneled in ivory, filled with music to melt the soul.
Among this king’s guests, those who are honored are honorable. To the bride, the psalmist reminds her to forget whence she came. Her real life is about to begin. How could she not submit and honor the groom as her lord? The wealthiest of the world will seek this king’s favor. Even the sight of his bride will make them feel humble. Her entourage is truly royal; anyone could see it. People would count themselves blessed beyond words just to catch a glimpse of such sights. The image is breathtaking.
And songs like this would never end so long as mankind lives on the earth, for his glory is eternal.
