When was the oral Torah given to Moses?
Was it at Sinai along with the written Torah
Or over the 40 years of wandering ?
Also how did Moses disseminate it to the Kohanin (Levites too?)
In like study groups over the 40 years, or all at once etc ?
I’m also wondering about the reiteration in the daily Torah study Deuteronomy Chapter 11 at the moment
Is that Moses giving out the oral Torah to complement the already given written Torah
or is it just reiteration & emphasis ?
