What all does the law include besides the Ten Commandments?
The law encompasses far more than the Ten Commandments: it includes the entire system of worship, the service of God, the priesthood, the tabernacle and temple, the sacrifices, and all the feast days of Israel's religious calendar.

Les explains that while people normally think of the law as only the Ten Commandments, the big picture of law was everything that pertained to the worship and the sacrifices, everything in the law. The service of God began when God gave the tabernacle to Moses and set up the priesthood with Aaron as the high priest. The services included how the priests operated, how the tabernacle was set up, how later the temple was set up, how the sacrifices were offered, and the setting up of all the feast days throughout Israel's religious calendar year. All of this was indicative and looked forward to our own plan of salvation, a picture of the coming Redeemer and the plan of salvation as we experience it today.
