You’ve got Moses, begging The Lord to enter the Promised Land, and reporting back that “The Lord said to me ‘Enough! Never speak to me of this matter again!’” (Deuteronomy 3:26).
You get God promising that observing the laws will be “proof of your wisdom and discernment to other peoples...” (4:6) and there you have it, the tradition of exceptional Jewish intelligence.
You get plenty of warnings to “Never Forget” ; for example: “But take utmost care and watch yourselves scrupulously, so that you do not forget the things that you saw with your own eyes and so that they do not fade from your mind as long as you live.” (4:9)
You get your Ten Commandments (one version of them, anyway...), you get your stone tablets, you get your Lord who “spoke to you out of the fire; you heard the sound of his words but perceived no shape -- nothing but a voice.” (4:12)
You get your advance warning of and explanation for the Diaspora:
When you have begotten children and children’s children and are long established in the land, should you act wickedly ... I call heaven and earth this day to witness against you that you shall soon perish from the land ... The Lord will scatter you among the peoples, and only a scant few of you shall be left ... There you will serve man-made gods of wood and stone, that cannot see or eat or smell. ( 4:25-28)Well, sort of. It probably wasn’t really advance warning; scholars figure Deuteronomy was written mostly after there’d already been some scattering.
Did I mention the Ten Commandments? Cue the thunderclouds.
