Isaiah 54:16-17

16Look! I myself created the worker who knows how to use iron to make things. He makes his fire very hot, and he makes weapons from the iron. He makes weapons that are strong to fight with. I also created the armies who use their weapons to destroy people.

17But nobody can make a weapon that will beat you, when your enemies attack you. If people accuse you of bad things, you will show that they are wrong. That is what the Lord will do as a gift for his servants. Yes, I will show that they are right.’ That is what the Lord says.
