Exodus Study: Chapters 30-31

In Chapter 30 God gives Moses more instructors about furnishing and items to be used in the tabernacle. We especially see the Altar of Incense, the ransom money, the basin, the anointing oil, and the incense itself. What does all this teach us about prayer and worship? In Chapter 31 God tells us who will build all of these things and re-emphasizes the Sabbath.
