How many words in the Hebrew and Greek Text?

From the first Hebrew word "B'resh ith" (In the beginning) in Genesis 1:1 to the last word "Amen" in Revelation 22:21, scholars (and computer programs) have counted 443,114 words in the original languages — 304,901 words in the Hebrew/Aramaic Old Testament, and 138,213 words in the Greek New Testament (latest NA28 edition).

Hebrew Torah
With the Hebrew Torah (the five books of Moses), since at least the days of Ezra (if not further back) the Jewish scribes not only counted the words but even the letters to ensure there would be no error in their transmission. The number of letters in the Torah is 304,805, and the number of words is 79,976. See Jesus's words Matthew 5:17-20. So there have been apparently zero variations in the written Torah (the first five books of Moses) since its Hebrew "template" model was set up by Ezra at the temple in Jerusalem around 400BC.

Hebrew Old Testament
And apparently minimal variations elsewhere. Most modern translations use the Biblia Hebraica Stuttgartensia based on the Leningrad Codex from the year 1008. Almost a hundred years older, but unfortunately no longer complete, is the Aleppo Codex from 930.
According to this article the Leningrad Codex and the Aleppo Codex are two prominent and exemplary instances of the so-called Masoretic Text, the version that was proclaimed definitive by Jewish scribes around 100 AD. Originally comprising only consonants, this text was provided with vowel marks as of about 700 AD. In this form, it was handed down further with meticulous care by the so-called Masoretes.

The Leningrad Codex has been housed at the National Library of Russia in Saint Petersburg since 1863, and has been the basic text for the Biblia Hebraica (Hebrew Bible) since 1937.

The KJV used the Second Rabbinic Bible (Mikraot Gedolot - Great Scriptures) published by Daniel Bomberg in Venice in 1524 with Jacob ben Hayyim as the printer.

According to this page, there are 1,196,824 letters in the Hebrew Old Testament as it is published today.

Greek New Testament
Critical Text is followed in most modern New Testament translations. It uses the original Greek based mostly on the 4th century Codex Vaticanus and Sinaiticus as published by Westcott Hort in 1881 — and contrasts, to a small degree, with the KJV (King James Version) and NKJV (New King James Version) that were based on 12th and 15th century Greek texts in the Textus Receptus published by Erasmus in 1516.

With the Critical New Testament, word counts differ fractionally. According to this discussion, the Tyndale House edition has 138,015 words, a difference to the NA28 edition of 198 words, or about 0.143%.

The Greek text of the Textus Receptus used in the KJV has close to 140,521 words. It includes many verses e.g. Acts 8:37 in the KJV that are only included as Footnotes in later translations e.g. the NIV click here.

Summing Up
So although there is no single "perfect" manuscript of the original language of the Bible (apart from the Torah, the first five books of the Old Testament) the functional differences between the published editions are minimal.

One scholarly account, Strongs Concordance first published in 1890, counted 8,674 unique Hebrew/Aramaic words excluding prefixes and suffixes with 641 words accounting for 80% of the Hebrew text. There are 5,523 unique words in Biblical Greek of which 319 account for 80% of the Greek text. For students with minimal (or zero) knowledge of the original alphabets, his numbering system has enabled them to start studying any Biblical Greek or Hebrew word by simply entering its code.

"And we hold more certain the prophetic word, to which you do well taking heed, as to a lamp shining in a dark place, until this day shall have dawned, and the Lightbearer shall have arisen in your hearts.
First knowing this, that any prophecy of scripture does not come into being of its own private interpretation.
For the prophecy was not brought at any time by man's choice, but being brought of the Holy Spirit, men spoke from God." 2 Peter 1:19-21
