Charles H. Spurgeon on Psalms 149:8

To bind their kings with chains, and their nobles with fetters of iron. Thus are the greatest enemies of Jehovah and his people reduced to shame, rendered helpless, and themselves punished. This was Israel's boast in actual fact, it is ours spiritually. The chief powers of evil shall be restrained and ultimately destroyed. Those who made captives of the godly shall themselves be made captive. The powers of evil cannot bind our King, but by his power their king shall be bound with a great chain, and shut up in the bottomless pit, that he may at length be trodden under the feet of saints.
