Only evidence the commandments were revealed before the exile is a document written long after the exile.  They weren't revealed by God to anyone on a mountain in Sinai, although you are free to argue they were revealed by God using the Babylonians.

Only evidence for what Jesus said is a collection of documents written after he was gone by people who had their own agendas.  Can get the outlines of what Jesus taught, but specificity is suspect.  
You are free to apply whatever definitions or labels you wish, if that is what you need.
