PILLAR : \Pil"lar\, a. (Mach.) Having a support in the form of a pillar, instead of legs; as, a pillar drill.

PILLAR :  used to support a building (Judg. 16:26, 29); as a trophy or memorial (Gen. 28:18; 35:20; Ex. 24:4; 1 Sam. 15:12, A.V., "place," more correctly "monument," or "trophy of victory," as in 2 Sam. 18:18); of fire, by which the Divine Presence was manifested (Ex. 13:2). The "plain of the pillar" in Judg. 9:6 ought to be, as in the Revised Version, the "oak of the pillar", i.e., of the monument or stone set up by Joshua (24:26).
