looked
This unhappy woman, says the Rev. T. Scott, "looked back," contrary to God's express command, perhaps with a hope of returning, which latter supposition is favoured by our Lord's words, "Let him not return back: remember Lot's wife." She was, therefore, instantaneously struck dead and petrified, and thus remained to after ages a visible monument of the Divine displeasure.
