C. F. Keil and Franz Delitzsch on Isaiah 13:13

Isa 13:13

Thus does the wrath of God prevail among men, casting down and destroying; and the natural world above and below cannot fail to take part in it. “Therefore I shake the heavens, and the earth trembles away from its place, because of the wrath of Jehovah of hosts, and because of the day of His fierce anger.” The two Beths have a causative meaning (cf., Isa 9:18). They correspond to ‛al-cēn (therefore), of which they supply the explanation. Because the wrath of God falls upon men, every creature which is not the direct object of the judgment must become a medium in the infliction of it. We have here the thought of Isa 13:9 repeated as a kind of refrain (in a similar manner to Isa 5:25). Then follow the several disasters. The first is flight.
