Lihatlah, Akulah yang menciptakan tukang besi, yang meniup api dalam arang dan menghasilkan senjata untuk keperluannya; dan Akulah yang menciptakan pembinasa untuk menghancurkan.
Tze'enah Ure'enah
“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.
Rashi
Behold I am He Who created a smith who devises a weapon, and I am He Who has created a destroyer that destroys it. That is, to say: I am He Who incited the enemy against you; I am He Who has prepared retribution for him.
Ibn Ezra
Behold, I have created the smith, etc. It is a figurative expression.
Rashi
and produces a weapon for his work For necessity. He completes it according to all that is necessary.
