For thou hast been a strength to the poor, & c.; for thou hast defended thy poor and helpless people against the fiercest assaults of their enemies. When the blast of the terrible one is as a storm against the wall; or, for (as this particle commonly signifies; or rather, therefore, as it is frequently used, because thou art their defender) the blast of the terrible, or strong, or violent one, was like a storm (of hail, or rain, or wind) against a wall, which makes a great and terrible noise, but without any effect, for the wall stands firm in spite of it. It is probable the prophet in these words had a special respect to that miraculous deliverance of Jerusalem from the rage and attempt of Sennacherib; although the words be general, and include other deliverances of a like nature.
