The entrance curtain (Ex 36:35-36:38)

“He made the curtain of blue, purple, and crimson yarns and fine twisted linen, with cherubim skillfully worked into it.  For it he made four pillars of acacia and overlaid them with gold.  Their hooks were of gold.  He cast for them four bases of silver.   He also made a screen for the entrance to the tent of blue, purple and crimson yarns, and fine twined linen, embroidered with needlework.  The five pillars had their hooks.  He overlaid their calyxes and their bases with gold, but their five bases were of bronze.”

The artisan made a curtain for the entrance with the colorful yarn and linen and fine needlework, just as it was prescribed in chapter 26.   However, there is more detail here.  There are four golden acacia pillars with golden hooks and four silver bases.  Thus this colorful entrance screen had pillars and bronze bases to make it stronger.
