The Numbering System of the Hebrew letters is often called Gematria. It is at least 2,800 years old - and probably older. The first documented use of Gematria is from an Assyrian inscription dating to the 8th century BC, commissioned by Sargon II. In this inscription, Sargon II states: "the king built the wall of Khorsabad 16,283 cubits long to correspond with the numerical value of his name."
SEE: Daniel Luckenbill, Ancient Records of Assyria and Babylonia, vol. 2, University of Chicago Press, 1927, pp. 43, 65.

Gematria has been used by Jewish scholars and teachers for thousands of years, causing some Bible readers to discredit the whole concept of Gematria, and dismissing the practice simply as Jewish "mysticism." However, not all uses of it are mystical, or even "evil".

GEMATRIA PRE-DATES KABBALAH This is evidenced by the fact that the Gematria Numbering System predates the ancient Jewish mystical system of Kabbalah, which did not emerge into the system that most would now associate with superstition, mysticism, magic incantations, and other occult influences, until the 12th or 13th century AD.

In fact, even in the NT book of Revelation, most renowned scholars see a reference to Gematria in Chapter 13. This verse concerns the antichrist, and the "number of his name."

"This calls for wisdom. Let the person who has insight calculate the number of the beast, for it is the number of a man. That number is 666." (Revelation 13:18).

EXPOSITOR'S GREEK NEW TESTAMENT COMMENTARY for Revelation 13:8 "[The apostle John] invites his readers to count the name or number of the Beast, i.e., to calculate a name whose letters, numerically valued on the principles of GEMATRIA."

BARNES" NOTES ON THE BIBLE [John here means] that somehow the number 666 would be expressed by his name in some well-understood method of computation.

MYER'S NEW TESTAMENT COMMENTARY [The mystery of the interpretation would be ] therefore according to the VALUE of the letters CURRENT WITH EVERY ONE [understood by its first readers]. The key to the mystery of the numerical name is, therefore, READILY FOUND; but wisdom and understanding are necessary in order to use this key properly.

THE TRANSCRIPT OF DR RUBINSTEIN'S STATEMENT IN THIS VIDEO

Dr Isaiah Rubinstein: "OK, listen carefully. In the year 1986, when most of you hadn't been born yet I was already a doctor and a scientist in the Weizmann Institute of Science. I researched the DNA mainly of mice, monkeys and Humans ...18,000 tissues of liver, kidneys, muscles and even a Human eye, I inspected them under a microscope. For your information, the optic microscope can magnify up to 10,000 times.

The digital microscope, on the other hand, can enlarge up to 1 million times! You really enter inside the cell. A digital microscope is not the regular one you are familiar with, it's basically a huge computer, you are looking through a screen and communicating with the software. Is that clear to everyone? This is science, not religion! So I communicated with this software, and I asked the software, "What is the force that holds the DNA attached?" The software responded that sometimes there is a sulphuric bridge,[Disulfide Bonds] which makes sure the DNA stays attached.(1)

Then I asked the million dollar question, listen carefully, I asked the software, "When does the bridge appear?" The software answer was that there are four nucleic acids which are the basis of the DNA chain: A, T, C & G. These are the acids which make up the DNA chain, that's a scientific fact! And the sulphuric bridge appears in the following manner: every ten acids there was a bridge, every five acids a bridge, every six acids a bridge ... and again every five acids were a bridge.

I was shocked! A sulphuric bridge that keeps the DNA attached. I was amazed. Who can tell me the meaning of 10-5-6-5? This is the numerical digit of Y-H-W-H (the name for God in the Hebrew Bible: YHWH).

Our Heavenly Father is in our DNA! Like a Rembrandt with a signature at the bottom of His artwork, God tell us, "I made you"! Our Heavenly Father signed His name in every cell of our body! I think I discovered God!"

AT THE TIME OF THE PRODUCTION OF THIS VIDEO - Dr Rubinstein was still with the Weizmann Institute of Science in Rehovot, Israel.

"Disulfide bonds can play an important role in stabilizing the tertiary structure of proteins, lowering the entropy of the three-dimensional structure."
[Translation: Sometimes there are sulfuric "bridges" that hold the DNA together - to keep it from collapsing in on itself - Just like Dr. Rubinstein said]
