Exodus 36:1-3

“And Bezalel and Aholiab, and every gifted artisan in whom the LORD has put wisdom and understanding, to know how to do all manner of work for the service of the sanctuary, shall do according to all that the LORD has commanded.” Then Moses called Bezalel and Aholiab, and every gifted artisan in whose heart the LORD had put wisdom, everyone whose heart was stirred, to come and do the work. And they received from Moses all the offering which the children of Israel had brought for the work of the service of making the sanctuary. So they continued bringing to him freewill offerings every morning.
