KJV:
Say unto the king and to the queen, Humble yourselves, sit down: for your principalities shall come down, even the crown of your glory.
NKJV:
Say to the king and to the queen mother, "Humble yourselves; Sit down, For your rule shall collapse, the crown of your glory."
NIV:
Say to the king and to the queen mother, "Come down from your thrones, for your glorious crowns will fall from your heads."
Interpretation:
God calls the king and queen mother to humble themselves and sit down. The verse warns that their authority will be taken away. The crown of their glory will fall. God uses the image of sitting down to show they must lower their position. When people exalt themselves, God may bring them down. The call to humble themselves shows that God offers them a chance to lower themselves before He lowers them. Those who humble themselves before God may avoid the judgment that comes from pride.
