Adam Clarke on Judges 16:29

The two middle pillars upon which the house stood - Much learned labor has been lost on the attempt to prove that a building like this might stand on two pillars. But what need of this? There might have been as many pillars here as were in the temple of Diana at Ephesus, and yet the two center pillars be the key of the building; these being once pulled down, the whole house would necessarily fall.
