Deuteronomy 4:2
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.
Proverbs 30:5-6
5. Every word of God is pure: he is a shield unto them that put their trust in him.
6. Add thou not unto his words, lest he reprove thee, and thou be found a liar.
I just want to quickly say that if you look at your Bible (that is not a KJV) there is something that has been changed, taken out, or put in.
Example: Matthew 18:11
For the son of man is come to save that which was lost.
This verse is not in the NIV, RSV,ERV, and 23 other Bibles.
