Moses gathered everyone together to tell them all the new rules God had made. He explained the resting on the Sabbath thing, and reminded them that they weren’t even allowed to build fire, since that was still work. He also let them know that the penalty for violating the Sabbath was execution.
Then Moses explained God’s plan for Its sanctuary and told everyone whose heart moved them to pony up the goods. So everyone was totally stoked and brought out all their treasures and jewels and yarn. Then Bezalel and Oholiab began overseeing all the inspired workers making the stuff that God demanded.
