The abstract noun "teaching" can be stated as "taught." AT: "Remember what I taught my servant Moses" (See: rc://en/ta/man/translate/figs-abstractnouns)

Remember

Here "Remember" stands for "Think about" and, at the same time, "Obey."

This is another name for Sinai.

Here "all Israel" is a reference to all the people in the nation of Israel. (See: rc://en/ta/man/translate/figs-metonymy)

These are the laws that God gave Israel for all time.
