Albert Barnes Commentary Psalms 89:44

"Thou hast made his brightness to cease, And cast his throne down to the ground." — Psalms 89:44 (ASV)

Thou hast made his glory to cease - Margin, "brightness." Luther, "Thou destroyest his purity." The original word means brightness, splendor.

The literal translation here would be, "You cause to cease from being brightness;" that is, you have taken away from his brightness, so that it is gone.

The allusion is to the splendor, the glory, the magnificence connected with his rank as king. This had been destroyed, or had come to nothing.

And cast his throne down to the ground - See Psalm 89:39.
