Revelation 2:27 - Matthew Poole's English Annotations on the Holy Bible

And he shall rule them with a rod of iron: an iron rod either signifies a right rod, that will not be easily bent and made crooked; or a severe rod, which is most probably the sense: see Psalms 2:9 Psalms 12:5. The words by the psalmist are applied to Christ, and to the church, Revelation 12:5: to particular saints here, who rule the nations either in Christ their Head, or with Christ as their Chieftain, with the word of God powerfully convincing the world of sin and righteousness. As the vessels of a potter shall they be broken to shivers; and all paganism and heathen idolatries shall be broken in pieces. Or, in the day of judgment, the saints that persevere shall sit with Christ, and judge and condemn the world severely; and then they shall be broken in pieces, never again to be sodered or cemented. Even as I received of my Father; for such a power and authority my Father hath given me, and I will give it to all them.
