What were the posts and boards of the outer court fence made of?
The posts and boards that formed the framework and stabilization of the outer court fence were made of wood covered with gold. The fence itself was constructed of pure white linen, but the supporting structure—posts, boards, and related framework—was wood overlaid with gold, as described in the tabernacle details.
Les teaches that the outer court fence or wall was constructed of pure white linen. The framework of that fence—the posts and the boards and so forth that stabilize it—were all made of wood covered with gold. He explains that every detail of the whole tabernacle is a picture of Christ and His work of the cross. The tabernacle was not going to stand very long until God said it was time to move on, and as the book of Exodus closes, the tabernacle is complete and going. In his review, Les reverses the order and moves from the outside, the outer court, to end up at the Ark of the Covenant.
