Silver rods were used to connect the pillars of the outer court together. The pillars have silver hooks near the top as well as at the bottom. One set of rods rested on the top hooks, and another set rested on the bottom hooks. The rods served as the top and bottom rails of the surrounding linen walls. The white curtains were fastened to the rods at the top and at the bottom, forming a continuous screen all around the tabernacle area.
