Numbers are used in Scripture, not merely as in Nature, with supernatural
design, but with spiritual significance, which may be summarized
as follow (*1) :--

ONE. Denotes unity, and commencement. The first
occurrences of words or utterances denote their essential significance,
in interpretation. Words that occur only once, in the originals,
are emphatic and important. First day, Light. The first occurrences
of all important words and expressions are noted in the margin.
TWO. Denotes difference. If two different persons
agree in testimony it is conclusive. Otherwise two implies
opposition, enmity, and division, as was the work
of the Second day. Compare the use of the word "double" applied to
"heart", "tongue", "mind", &c.
THREE. Denotes completeness, as three lines complete a
plane figure. Hence, three is significant of Divine perfection and
completeness. The third day completes the fundamentals of creation-work.
The fourth, fifth, and sixth days are the counterpart and repetition of
the first, second, and third, and correspond respectively. (See the
structure of Gen. 1, p. 3.) The number, three, includes resurrection
also; for on the third day the earth rose up out of the deep, and
the fruit rose up out of the earth.
FOUR. Denotes creative works (3+1), and always has reference
to the material creation, as pertaining to the earth, and things
"under the sun", and things terrestrial.
FIVE. Denotes Divine grace. It is 4+1. It
is God adding His gifts and blessing to the works of His hands. The
Heb. Ha'aretz (the earth), by "Gematria" (i.e. the addition
of the numerical value of the letters together) is a multiple of four,
while Hashamayim (the heavens) is a multiple of five. The
Gematria of Caris (charis), the Greek
for Grace, is also a multiple of five. It is the leading factor
in the Tabernacle measurements.
SIX. Denotes the human number. Man was created on
the sixth day; and this first occurrence of the number makes it
(and all multiples of it) the hall-mark of all connected with man.
He works six days. The hours of his day are a multiple of six.
Athaliah usurped the throne of Judah six years. The great men who
have stood out in defiance of God (Goliath and Nebuchadnezzar and Antichrist)
are all emphatically marked by this number.
SEVEN. Denotes spiritual perfection. It is the number
or hall-mark of the Holy Spirit's work. He is the Author of God's
Word, and seven is stamped on it as the water-mark is seen in the manufacture
of paper. He is the Author and Giver of life; and seven is
the number which regulates every period of Incubation and Gestation, in
insects, birds, animals, and man.
EIGHT. Denotes resurrection, regeneration; a new beginning
or commencement. The eighth is a new first. Hence the octave
in music, color, days of the week, &c. It is the number which
has to do with the LORD, Who rose on the eighth, or new "first-day".
This is, therefore, the Dominical
number. By Gematria (see
above), 'JJjjIhsous (Jesus) makes the
number 888. It, or its multiple is impressed on all that has to do
with the Lord's Names, the Lord's People, the Lord's works.
NINE. Denotes Finality of judgment. It is
3x3, the product of Divine completeness. The number nine,
or its factors or multiples, is seen in all cases when judgment
is the subject.
TEN. Denotes Ordinal perfection. Another new first;
after the ninth digit, when numeration commences anew.
ELEVEN. Denotes disorder, disorganization, because it
is one short of the number twelve (see below).
TWELVE. Denotes Governmental perfection. It is the
number of factor of all numbers connected with government : whether
by Tribes or Apostles, or in measurements of time, or in things which have
to do with government in the heavens and the earth.
THIRTEEN. Denotes rebellion, apostasy, defection, dis-integration,
revolution, &c. The first occurrence fixes this (Gen. 14:4);
and the second confirms it (Gen. 17:25). It, and its multiples, are
seen in all numbers, and in the Gematria (see above) of all names and passages
that are associated with rebellion, &c.
SEVENTEEN. Denotes a combination of spirit and order
(10+7). It is the seventh prime number (as 13 is the sixth prime
number).
Other numbers follow the laws which govern the smaller, as being their
factors, sums, products or multiples : e.g. 24 is 12x2, a higher
form of 12.

25 = 5^{2}. Grace
intensified.
27 = 3^{3}. Divinity
intensified.
28 = 7x4. Spiritual perfection
in connection with the earth.
29 = 3^{3}. Intensifying
of Divine judgment.
30 = 3x10. Divine perfection, applied to order.
40 = 10x4. Divine order applied to earthly
things. Hence, the number of probation.

The four perfect numbers, 3, 7, 10, and 12, have for their product
the remarkable number 2,520. It is the Least Common Multiple of the
ten digits governing all numeration; and can, therefore, be divided by
each of the nine digits, without a remainder. It is the number of
chronological perfection (7x360).
