If six is the number of secular or human perfection, then 66 is a more emphatic expression of the same fact, and 666 is the concentrated expression of it; 666 is therefore the trinity of human perfection; the perfection of imperfection; the culmination of human pride in independence of God and opposition to His Christ.
There are Three Men
There are three men which stand out in Scripture as the avowed enemies of God and of His people. Each is branded with this number six that we may not miss their significance:
1. GOLIATH, whose height was 6 cubits, and he had 6 pieces of armour;* his spear's head weighed 600 shekels of iron (1Samuel 17:4-7).
2. NEBUCHADNEZZAR, whose "image" which he set up,** was 60 cubits high and 6 cubits broad (Daniel 3:1), and which was worshipped when the music was heard from 6 specified instruments,*** and
3. ANTICHRIST, whose number is 666.
* In Ephesians 6:14-18, the Christian's armour has a seventh piece—"Prayer." See under "Seven."
** We must distinguish the "image" which he set up, from the "man" of whom he afterwards dreamt. The proportions are not the same. The height of a man is to his breadth not as 10:1. Some have therefore thought that this "image" may have been an obelisk. But as the word for "image" denotes a form or likeness, it may have been like the form of a man standing on a pedestal of which the height was included. The pedestal being probably 24 (6x4) cubits, and the image 36 (6x6).
*** The numerical value (by gematria) of the words in Daniel 3:1, which describe the setting up of this image is 4662. The very figures are significant, but still more so are the factors of this number. 4662 = 7 x 666.
In the first we have one six connected with the pride of fleshly might.
In the second we have two sixes connected with the pride of absolute dominion.
In the third we have three sixes connected with the pride of Satanic guidance.
Jerusalem was Trodden Down
Jerusalem was trodden down by the Roman Empire exactly 666 years from the battle of Actium, BC 31, to the Saracen conquest in AD 636.*
The Talents of Gold
The talents of gold brought to Solomon in a year were 666 (1 Kings 10:14). But this perfection of money-power was only "vanity and vexation of spirit" (Eccl 2:8,11; compare 1Timothy 6:10).
As to the triple number 666, we have already seen (see note in discussion on number 3) that while one figure (6) is significant, two figures (66) are still more so; and three figures (666) seem to denote the concentration or essence of the particular number.
We see further examples of this in
Jesus, 888, the dominical number;
Sodom, 999, the number of judgment;
Damascus, 444, the world number;
The beast, 666, the number of man.
"Verily, verily, I say unto you," 888;
The Lord God made, 888; etc., etc.
"The children of Adonikam" who returned from the Captivity (Ezra 2:13) numbered 666. Adonikam means the lord of the enemy. This is suggestive, even though it may be vague.
The number 666 has another remarkable property. It is further marked as the concentration and essence of 6 by being the sum of all the numbers which makes up the square of six! The square of six is 36 (62, or 6x6), and the sum of the numbers 1 to 36 = 666, i.e., 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 + 21 + 22 + 23 + 24 + 25 + 26 + 27 + 28 + 29 + 30 + 31 + 32 + 33 + 34 + 35 + 36 = 666
May God help me with my ongoing research to learn and truly understand..
