1) 666 meaning a biblical allusion to Adonikam in the Old Testament.
2) The Holy Spirit inspired this Riddle to strengthen the faith of the generation alive in the End Time fighting against unprecedented apostasy (2 Th. 2:3-4; 1 Tim. 4:1; 2 Tim. 4:2). and mockery of God’s Word the Bible (Jude 1:18; 1 Tim. 3:1-5; 2 Pet. 3:3). Adonikam’s name will be the actual name of the Beast that rises and the solution indicates both Providential Preservation and Inerrancy of Scripture are true, as both 666 and 667 are correct and God prevented copiests from reconciling the number as modern textual critics are wont to do.
We solve riddles by heeding its details, spotting double entendre hinting at a solution. For example, Samson’s riddle (Judges 14:14) was solvable by the double entendre on “lion” and “honey” (Judges 14:8-9, 18):
So he said to them: “Out of the eater came something to eat, And out of the strong came something sweet.” Now for three days they could not explain the riddle. (Jdg. 14:14) NKJ
The word “lion” in Hebrew (ʾarî) is almost identical to an Arabic word for “honey” (ʾary).-Wolf, H. (1992). Judges. In F. E. Gaebelein (Ed.), The Expositor’s Bible Commentary: Deuteronomy, Joshua, Judges, Ruth, 1 & 2 Samuel (Vol. 3, p. 468). Grand Rapids, MI: Zondervan Publishing House.
Lets Solve what 666 meant to John:
Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six. (Rev. 13:18) KJV
The Genitive (“OF”) is the double entendre. 1) 666 is the number OF a man; 2) 666 is the number OF a name (Rev. 13:17); 3) 666 is the number OF the Beast.
1a) 666 is OF the man because he has 666 children (Ezr. 2:13).
2a) 666 is OF the name because it generates the equation that results in 666. In Nehemiah 7:18 Adonikam is said to have 667 children, therefore its deducible the list began with Adonikam’s father who must also be named Adonikam. So the “count” or “calculation” which is “OF” this name is 667-1=666, pointing to the same man Adonikam his son (Neh. 7:18).
3a) 666 is OF the Beast because John said so (Rev. 13:18).
The children of Adonikam, six hundred sixty and six. (Ezr. 2:13) KJV
The children of Adonikam, six hundred threescore and seven. (Neh. 7:18) KJV
Having these two verses point to the same name is like having “two witnesses” establishing the matter (Deut. 19:15).
