Exodus 36:35-38

Moreover, he made the veil of blue and purple and scarlet material, and fine twisted linen; he made it with cherubim, the work of a skillful workman. He made four pillars of acacia for it, and overlaid them with gold, with their hooks of gold; and he cast four sockets of silver for them. He made a screen for the doorway of the tent, of blue and purple and scarlet material, and fine twisted linen, the work of a weaver; and he made its five pillars with their hooks, and he overlaid their tops and their bands with gold; but their five sockets were of bronze.
