In Exodus 31 we read the final instructions that are given in regards to the Tabernacle. Several foreman are appointed and the final charge is given to commence the building project that has been commissioned by God. And then, as the final and seventh part of the instructions that have been the topic of the text since Exodus 25, the command is given to keep the Sabbath. There is in this chapter, a contrast between work and Shabbat. Two ends of a spectrum that we all engage in.
