Did moses reveal Yahweh's commandments to the Hebrews?

Answer 1

That depends on ones interpretation of history and religion. The Hebrews invaded the lands of Canaan and eventually created the nation of Israel. This nation was not entirely populated by the decedents of the Hebrews nor were all the Hebrews present in this land. Some time after this many Israelis became slaves to the Egyptians - either because the Israelis invaded Egypt or Egypt invaded Israel (the difference is found between historical text and religious text). A generation after the initial enslavement the Israelis were freed and went back to Israel. At this time an invading army came to Israel and conquered the southern portion creating the land of Judah. Judah is were the term Jew comes from. The modern day religion of Judaism and the ethnic Jews come from this nation. The invading force was either the returning Israelites (following the teachings of Moses) of Egyptian followers of Moses. (again there are differing views as to the history). Either way the commandments of Yahweh that Moses obtained were given to these followers/invaders and they formed the bases of the new Jewish religion. So it is debatable weather Moses gave the law to the Hebrews (or the Israelis or the Egyptians) but the laws were given to those that latter became the Jews.
