“Ye shall not add unto the word which I command you, neither shall ye diminish ought from it, that ye may keep the commandments of the LORD your God which I command you.” (Deuteronomy 4:2)

In addition to the numerous times when the writers of the Bible asserted that what they wrote came directly from God (e.g., Leviticus 1:1; Jeremiah 1:4; Revelation 1:1), there are at least four warnings against tampering with these revealed words.

The first is our text above, in which Moses commanded neither to add to nor diminish from anything he had written. This warning was supplemented later with the following: “What thing soever I command you, observe to do it: thou shalt not add thereto, nor diminish from it” (Deuteronomy 12:32).

Moses wrote the opening books of the Bible, and it was appropriate that he should give such a warning. The last warning was by John at the very end of the whole body of Scripture, and his warning was even more severe. “If any man shall add unto these things, God shall add unto him the plagues that are written in this book: And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life” (Revelation 22:18-19).

Since John was the last apostle, it is clear that this warning is against any later attempt to add some new “revelation” to the now-complete Word of God.

Then, very near the middle of the Bible, there is this: “Every word of God is pure:...Add thou not unto his words, lest he reprove thee, and thou be found a liar” (Proverbs 30:5-6). And remember also the words of Christ: “Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled” (Matthew 5:18). So, don’t mess with the Word of God! HMM
