Question

In this first encounter with God on Sinai (Horeb), Moses learned all the following lessons except :

Answer 1

What Moses did NOT learn at his first encounter with God at Horeb (Sinai):

• that God would, by Moses, give Israel the Law there later.

Further details:

The account of Moses' first encounter with God is recorded in Exodus chapter 3.  This happened during the years that Moses had fled from Egypt after he had killed an Egyptian overlord who had been beating a Hebrew slave (cf. Exodus 2:11-25).   The account of Moses' encounter with God at Horeb begins this way (Exodus 3:1-3 NIV):

• Now Moses was tending the flock of Jethro his father-in-law, the priest of Midian, and he led the flock to the far side of the wilderness and came to Horeb, the mountain of God. There the angel of the Lord appeared to him in flames of fire from within a bush. Moses saw that though the bush was on fire it did not burn up.  So Moses thought, “I will go over and see this strange sight—why the bush does not burn up.”

All of the listed items in your question were things that God revealed to Moses through his appearance at the burning bush -- except for the fact that later, on this same mountain, God would deliver the Torah (the Law) for his people Israel.  After God used Moses' leadership to deliver the Hebrew people out of Egypt, as they journeyed up toward Canaan (the future land of Israel), they came to the mountain of Sinai and encamped there.  The account of Moses' encounters with God again on that mountain, receiving the Law from God, is also recorded in the Book of Exodus, beginning at chapter 19.
