'Pillars' in the Bible

Cedar-trees are the pillars of our house; and our boards are made of fir-trees.

Who is this coming out of the waste places like pillars of smoke, perfumed with sweet spices, with all the spices of the trader?

He made its pillars of silver, its base of gold, its seat of purple, the middle of it of ebony.

His legs are as pillars of stone on a base of delicate gold; his looks are as Lebanon, beautiful as the cedar-tree.
