“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
I know lots of people who like the “diminish” part, but I’ve never heard anyone that understood the “add” part.
For extra effect:
“Also I have made a decree, that whosoever shall alter this word, let timber be pulled down from his house, and being set up, let him be hanged thereon; and let his house be made a dunghill for this.”
Just a thought- for next time we assume that our own convictions trump the Bible.
