In Genesis 22:13, this signifies with all power as to the truths of faith. (Arcana Coelestia 2832) Horns are mentioned in the Word here and there, and signify the power of truth from good, or, in the opposite sense, of falsity from evil. Here they signify that the spiritual are entangled in external knowledges of the natural with all power as to truth; but are deprived of the power of receiving truth. (Arcana Coelestia 2832)

In Revelation 8:11, this signifies power in speaking, teaching, and writing, consequently, in reasoning and arguing.

'The little horn that rose up,' as mentioned in Daniel 7:3-8, signifies the full perversion of the Word by the application of its literal sense to the confirmation of the love of dominion. It is called 'little,' because such perverted application is not sensibly apparent to the understanding of a person, or to the sight of his spirit.

When spoken of the Lord, a 'horn' signifies omnipotence. It also stands for the power of truth from good.

1782. The heifer, she-goat, and ram are representatives of the celestial things of the Church, while the turtle dove and the fledgling are representatives of the spiritual things of the same, verse 9. The Church was on one side, the Lord on the other, verse 10. The Lord would disperse evils and falsities, verse 11. But falsities would continue to infest it, verses 12-13. From those falsities there would be deliverance, verse 14, and so the Lord would experience comfort, verse 15. Evils however would take possession of it, verse 16, and in the end nothing but falsities and evil desires would reign there, verse 17. At this point the Lord's kingdom would come, and a new Church, the extension of which is described, verse 18. The falsities and evils that were to be expelled from it are the nations mentioned in verses 19-21.
