Commentary on Daniel 7:24

• John Calvin (Reformed), Calvin's Commentaries on Daniel 7:24: He afterwards adds, The ten horns are the ten kings which should arise These Ten Kings are clearly comprehended under one empire, and there is no question here of separate persons. In the Persian kingdom, we observed many kings, and yet the image of the second beast was single, while it embraced all those kings until the change occurred.
• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on Daniel 7:15-28: Here we have, I. The deep impressions which these visions made upon the prophet. God in them put honour upon him, and gave him satisfaction, yet not without a great allay of pain and perplexity (Dan 7:15): I Daniel was grieved in my spirit, in the midst of my body.
• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on Daniel 7:24: And the ten horns out of this kingdom are ten kings that shall arise,..... Or ten kingdoms which sprung out of the Roman empire, or into which it was broken and divided upon the dissolution of it, about A.D. 476; which, according to Mr. Mede (k), were thus divided, A.D. 456, 1. Britons; 2. Saxons; 3. Franks; 4. Burgundians; 5 Visigoths; 6. Suevians and Alanes; 7. Vandals; 8. Almanes; 9.
• Jamieson-Fausset-Brown (Reformed), Commentary Critical and Explanatory on the Whole Bible on Daniel 7:24: ten horns--answering to the ten "toes" (Dan 2:41). out of this kingdom--It is out of the fourth kingdom that ten others arise, whatever exterior territory any of them possess (Rev 13:1; Rev 17:12). rise after them--yet contemporaneous with them; the ten are contemporaries. Antichrist rises after their rise, at first "little" (Dan 7:8); but after destroying three of the ten, he becomes greater than them all (Dan 7:20-21).
