“For the authority of the horses is in their mouths and in their tails; for their tails are like serpents and have heads, and with these they do harm.” (Revelation 9:19)

The John class and the great crowd have left behind a stinging message, corresponding to “tails,” in the thousands of millions of Bibles, books, brochures, and magazines distributed over the years. To their opponents, who are advised of the coming “harm” from Jehovah, these armies of cavalry truly seem like two myriads of myriads.​—Compare Joel 2:4-6.

By using updated printing methods, this numerous cavalry in the 68 years before 2005 was able to distribute, in upwards of 450 of earth’s languages, billions of Bibles, books, magazines, and brochures​—many times more than a literal two myriads of myriads.
