Today we discuss the mysterious phrase 8:12 - 'אכתוב לו רובי תורתי כמו זר נחשבו' Either: "Though I write for him the great things of MyTorah, they are reckoned a strange thing"Or the Midrash (Tanchuma Ki Tissa 34):

"I write the majority of the Torah [but leave the Mishnah unwritten] so that the [Oral Torah] remains undecipherable [strange] to the Nations of the World.
