Nahum 3:14

Draw thee waters, fill all thy cisterns, and make more that thou want not for drink, yea, draw the waters into the ditches about every fort, for the siege, which thine enemies will lay against thee. Fortify; repair all decays, and strengthen all that is weak. Go into clay, and tread the mortar; set thy brick-makers on work to prepare store of strongest bricks. Make strong the brick-kiln, that the materials for thy fortifications may be firm and good. All this is spoken with an irony, or derision of their fruitless labour.
