Exodus 31:1-18

31:1-5 | Bezalel, a master craftsman, had a particular skill that was needed for worship: he was filled with the Spirit of God (a phrase typically used in the OT for prophets and kings). For those who are willing, the Lord can and will use every gift He provides His servants as a means to worship Him.

31:12-17 | Instituted on Mount Sinai, the Sabbath was a sign of the distinct and special relationship between the Lord and Israel. The basic idea of Sabbath is not worship but rest from work.
