God is now speaking to the second generation of wilderness wanderers. The first generation has died out and the Lord now speaks to their sons and daughters. God is commanding them to not do what their parents did to defile themselves with the idols their fathers worshipped. He urged them to follow the Law He provided to them at Sinai. He wanted them to sanctify (make holy) the sabbaths as signs of the covenant relationship between the Lord and themselves. By following these instructions the second generation would come to know by personal experience that Jehovah was their God. As they would worship Him and keep His Laws He would reveal more of Himself to them through blessings. This group was to be just a rebellious as the first. They worshipped idols while they offered sacrifices and offerings to the Lord syncretistically (Amos 5:25-27).
