Rev. 10:11 – And I was told, “You must prophesy again about many peoples, nations, languages, and kings.” (HCSB)
You must prophesy again (v. 11)
Finally, John is told he “must prophesy again about many peoples, nations, languages, and kings” (v. 11). Another possible translation is that John must prophesy “against” or “concerning” many peoples. While the Lamb redeems a countless throng from every tribe, language, people and nation (Rev. 5:9; 7:9-17), there are hoards of stiff-necked unbelievers who resist the gospel John preaches, war against Christ and His people, and bring upon themselves certain destruction (Rev. 11:9; 13:7; 17:15; 19:11-21). Kings in particular will take their stand on the side of evil and will pay dearly for it (Rev. 6:15; 16:12-14; 17:2, 18; 19:18-19).
“The apostle is made to know that this book of prophecy, which he had now taken in, was not given him merely to gratify his own curiosity, or to affect him with pleasure or pain, but to be communicated by him to the world” (Matthew Henry’s Commentary on the Whole Bible: Complete and Unabridged in One Volume, Rev. 10:8-10).
