Psalms 89:39

Thou hast (d) made void the covenant of thy servant: thou hast profaned his (e) crown [by casting it] to the ground.

(d) Because of the horrible confusion of things, the prophet complains to God, as though he did not see the performance of his promise and thus discharging his cares on God, he resists doubt and impatience.

(e) By this he means the horrible dissipation and tearing of the kingdom which was under Jeroboam, or else by the Spirit of prophecy Ethan speaks of those great miseries which came to pass soon after at the captivity of Babylon.
