פּירוש אויף ישעיהו 54:16

“It is I who have created the smith, etc.” [54:16]. The Holy One said: how good. Though Gog and Magog will come against you with swords, bows and arrows, and all the weapons of war, do not fear. I have created the people who make the weapons of war. Everything is in my hands and I can protect you from them. I have created the smith who blows on the coals to make them hot to make the iron from which swords are made. Whatever he wants to make, I can disrupt the same person from his craft, even more so I can destroy the swords, so that they cannot do anything to you. Concerning this, God says in the verse “it is I who created the ravager to destroy” [54:16]. I have created a ravager who destroys what I want. Therefore, do not fear the weapons.⁵Radak, Isaiah, 54:16.
