'Pillars' in the Bible

(The Shulammite Bride)“What is this coming up from the wildernessLike [stately] pillars of smokePerfumed with myrrh and frankincense,With all the fragrant powders of the merchant?”

“His legs are [strong and steady] pillars of alabasterSet upon pedestals of fine gold.His appearance is like Lebanon,Stately and choice as the cedars.
