What was God getting ready to establish for Israel's worship?
God was getting ready to establish the ecclesiastical part of the law—Israel's tabernacle worship, which would later be associated with the temple. This worship system was given at Mount Sinai, and the tabernacle was a tent, indicating its temporary nature.
Les teaches that God was preparing the nation of Israel at Mount Sinai. They had already been given the law, the Ten Commandments, and a certain amount of the civil law in the intervening chapters. Now God was getting ready to set up the ecclesiastical part of the law, which establishes what would later be called their temple worship. At this point, it would be a tabernacle—a tent—which is temporary.
