Judges 16:26 - Joseph Benson’s Commentary on the Old and New Testaments

The pillars whereon the house standeth It is probable that this house, whether it were a temple or theatre, was no more than a wooden building, raised for the present occasion, much in the form of an amphitheatre, in the midst of which were two large wooden pillars, on which the main beams of the roof rested, so that if these should be pulled away, the building must necessarily fall. Pliny, in the fifteenth chapter of the thirty-sixth book of his Natural History, speaks of two theatres, built by C. Curio, in Julius Cesar's time, each of which was supported only by one pillar, though many thousands of people sat together in it; and mentions the fall of an amphitheatre, by which fifty thousand people were killed or wounded.
