21 Heb “for all the work, to do it.” This lengthy section (35:1–36:7) forms one of the most remarkable sections in the book. Here there is a mixture of God’s preparation of people to do the work and their willingness to give and to serve. It not only provides insight into this renewed community of believers, but it also provides a timeless message for the church. The point is clear enough: In response to God’s commission, and inspired by God’s Spirit, the faithful and willing people rally to support and participate in the Lord’s work.
