Bible Compare was initially developed to compare the 1769 edition of the Authorized Version to the 1611 edition. There has been much confusion and disinformation over the years concerning the differences between these editions. Some insist there are thousands of differences between them, indicating the current edition is a heavy revision of the original. Often this argument is used to justify the many differences between the AV and the modern versions. However, Bible Compare can quickly get to the truth of the matter.

The Comparison feature incorporated within Bible Analyzer will only compare the 1611 edition of the AV and the ASV with the 1769 edition. However, Bible Compare will compare any two properly formatted Bibles or other texts. Furthermore, Bible Compare has added features not available in the Bible Analyzer edition

Bible Compare uses brackets, a bold font, and color coding to reveal the differences in texts. Below is an example of Matt. 1:25 comparing the Authorized Version 1769 text and the ASV (with punctuation and case ignored),
Mat 1:25,
and knew her not till she had brought forth [a] [her] [firstborn] son and he called his name jesus
The Dark Red "[a]" indicates the word "a" is added to the default text (here the AV).
The Dark Blue
"[her] [firstborn]" shows the words "her firstborn" are omitted.

In short,
Dark Brown =  added
Dark Blue =  subtracted

The normal black text with the dark blue is the reading of the default (first) text. The black text with the dark red is the reading of the second text.

A Quick Example

In the chart below we list the number of differences between the 1769 edition and the 1611 edition along with some modern versions which claim to be a revision of the Authorized Version to show the differences. The book of Titus will be analyzed with all differences in case and punctuation ignored (with the 1611 edition spelling and compound words are also ignored).    

Version Differences from 1769 edition in Titus
AV-1611 0
RV 375
ASV 400
RSV 911
NASV 777
NIV 1022
NKJV 449
KJ2000 187

Bible Compare's
count of differences is agressive. It counts every added and subtracted difference. This is the best way to receive consistant results. For instance, if there is only one word changed in a verse Bible Compare will count that as TWO differences. One word subtracted and one word added.

As one can see, there is no differences between the 1611 edition and the 1769 edition in the book of Titus apart from spelling, punctuation, and word case. However, there are many differences with the newer versions. True, a few of the differences may be due to spelling, but the vast majority are textual differences.

The best Bible texts to use are those from They are formatted properly and have text information embedded in the file which Bible Compare can recognize. If other texts in a different format are used the results may not be consistant. Also, they will be identified within Bible Compare as simply "Text 1" and "Text 2."

Spelling Differences

Bible Compare to ignore all the spelling differences between the 1611 and 1769 editions of the AV a matching dictionary must be used. Bible Compare uses "regular expresions" and an extensive built-in dictionary to deal with the spelling differences . It is essentially complete for the New Testament, but to keep the program running at a reasonable speed the Old Testament spelling differences (other than those of the New Testament) have not been implimented.

Even with the matching dictionary, all the spelling differences cannot be removed. The 1611 edition is not always consistant in spelling and some of it spelling for a word is the same as the modern spelling of a different word.

For instance the 1611 edition spells the word "marry" as "mary." These words cannot be transposed or every instance of "Mary" would become "marry." "Then" and "than" is another case. Another trait of 1611 spelling is the use of what looks like "ye" as "the." The appearant "ye" was more of a symbol to represent "the" in those days It did not mean the word "ye". If one will look at an original printing of the 1611 edition it is clear the "ye" is not the same as the word "ye," but when the text was converted to ascii computer file format it came out as "ye". Nevertheless, for obvious reasons these differences must remain. 

Although much more consistent the 1769 edition also has spelling variations. For instance, the spelling "born" is used in most instances, however, the spelling "borne" is also used (John 5:37). In this case the 1611 edition reverses roles and has the current spelling "born."
These cases are relatively few and can easily be considered when viewing the results.

The spelling matching is done in stages thus the display may show a 1611 edition word with current spelling. This is usually a result of a two words being matched with a corresponding single compound word. Bible Compare will update one of the single words but may fail to match with the compound word. As a result the updated word will be marked in the display.   

Although the spelling matching is not flawless, it eleminates the vast majority of differences making the few true textual differences easy to find.
