Say unto them which daub it with untempered morter, that it shall fall: there shall be an overflowing shower; and ye, O great hailstones, shall fall; and a stormy wind shall rend it.
There shall be an overflowing shower - "overflowing," inundating; such as will at once wash away the mere clay mortar. The three most destructive agents shall cooperate against the wall-wind, rain, and hailstones. These last in the East are more out of the regular course of nature, and are therefore often particularly specified as the instruments of God's displeasure against His foes (Exodus 9:18; Joshua 10:11; Job 38:22; Psalms 18:12-13; Isaiah 28:2; Isaiah 30:30; Revelation 16:21). The Hebrew here is literally, stones of ice. They fall in Palestine, at times an inch thick, with a destructive velocity. The personification heightens the vivid effect, 'O ye hailstones.' The Chaldeans will be the violent agency whereby God will unmask and refute them, overthrowing their edition of lies.
