[Avodah] The 10 Dibros are split into 2 x 5

[Arie Folger]

Rabausai,

It is well known that one way to analyze the 10 dibrot is that they consist of 
5 bein adam laMaqom and 5 bein adam le'havero. While I did find the division 
of the dibrot into 5+5 in massekhet Sheqalim daf khaf vav (IIRC) and in the 
Yalqut Shim'oni parsaht Terumah §368, they do not mention the BAL'H vs. BALM 
distinction. The earliest source I found so far is the Ramban on lo tirtza'h 
in the dibrot of Parshat Yitro (passuq 13).

Does anyone know of an earlier source than the Ramban for this analysis?

KT,
