Keep thyself, and do all that I command you; thou shalt not add to it nor diminish from it.
Ye shall not add unto the word which I command you, neither shall ye diminish anything from it, that ye may keep the commandments of the LORD your God which I command you.
Only be thou strong and very courageous that thou mayest keep and do according to all the law, which Moses my slave commanded thee; turn not from it to the right hand or to the left that thou may be prospered in all the things that thou doest.
For I testify unto everyone that hears the words of the prophecy of this book, If anyone shall add unto these things, God shall add unto him the plagues that are written in this book;
when thou shalt hearken to the voice of the LORD thy God, keeping all his commandments which I command thee this day, to do that which is right in the eyes of the LORD thy God.
teaching them to observe all things whatsoever I have commanded you; and, behold, I am with you always even unto the end of the age. Amen.
