To bind their kings with chains, and their nobles with fetters of iron. Which is thought to allude to what was done to the Canaanitish kings, in the times of Joshua; and to the princes of Midian by Gideon; and to Agag by Saul; and to the Ammonites, Syrians, and others, by David: but it refers either to the first times of the Gospel, and the influence of the sword of the Spirit over the hearts of men; and on some very great personages, as kings and nobles, brought to Christ and his churches, in chains of powerful and efficacious grace, declaring a ready and cheerful subjection to his Gospel and ordinances; such as Constantine, Theodosius, and others; and who were instruments in subduing, conquering, and destroying tyrannical and persecuting emperors and princes, as Maximilian, Licinius, and others; see Isa 45:14; and more instances of the power of the Gospel, and the influence of divine grace on such persons, there will be in the latter day; see Isa 49:23.
It may also respect the use of the Gospel ministry, compared to a twoedged sword on the hearts of men in common; whereby Satan, the strong man armed, who keeps the palace as a king or prince, is dispossessed; and sin, which reigns like a king unto death, is dethroned, and grace is set up as a governing principle.
