Just when things seemed to be going so well. In faithfulness to his promises, the Lord has blessed the descendants of Abraham, rescuing them from Egypt and bringing them to Mount Sinai where he has entered into a unique, exclusive, one-of-a-kind relationship with them. The Lord has promised to be their god and the Israelites have promised to be his people. Then, as Moses is receiving the instructions for the tabernacle so that the Lord can live with his people, they go and do something that jeopardises the whole thing. Will there be a happy ending here? Or destruction in the wilderness?
