Various Bible scholars, past and present, reached the same conclusion—that is, the number is literal. For instance, in commenting on Revelation 7:4, 9, British lexicographer Dr. Ethelbert W. Bullinger observed some 100 years ago: “It is the simple statement of fact: a definite number in contrast with the indefinite number in this very chapter.” (The Apocalypse or “The Day of the Lord,” page 282) More recently, Robert L. Thomas, Jr., professor of New Testament at The Master’s Seminary in the United States, wrote: “The case for symbolism is exegetically weak.” He added: “It is a definite number [at 7:4] in contrast with the indefinite number of 7:9. If it is taken symbolically, no number in the book can be taken literally.”—Revelation: An Exegetical Commentary, Volume 1, page 474.
