Discovery BoxExodus 36:37-38 
Context36:37 He made a hanging for the entrance of the tent of blue, purple, and scarlet yarn and fine twisted linen, the work of an embroiderer, 36:38 and its five posts and their hooks. He overlaid their tops 1 and their bands with gold, but their five bases were bronze. 2
1 tn The word is “their heads”; technically it would be “their capitals” (so ASV, NAB, NRSV). The bands were bands of metal surrounding these capitals just beneath them. These are not mentioned in Exod 26:37, and it sounds like the posts are to be covered with gold. But the gradation of metals is what is intended: the posts at the entrance to the Most Holy Place are all of gold; the posts at the entrance to the tent are overlaid with gold at the top; and the posts at the entrance to the courtyard are overlaid with silver at the top (S. R. Driver, Exodus, 387, citing Dillmann without reference).
