Thou therefore gird up thy loins, and arise, and speak unto them all that I command thee: be not dismayed at their faces, lest I confound thee before them.
Ye shall not add unto the word which I command you, neither shall ye diminish aught from it, that ye may keep the commandments of the Lord your God which I command you.
