FTR this is Deuteronomy 4:2:
Do not add to what I command you and do not subtract from it, but keep the commands of the L-RD your G-d that I give you. (NIV)But then I have no dog in this fight.
ML/NJ
And now, as pertaining to this law, verily, verily, I say unto you, I will reveal more unto you, hereafter; therefore, let this suffice for the present.
Looks like GOD, on the one hand; laid down ALL of the 'law';
while on the other; just let snippets of it dribble out...
