Isaiah 54:17

15 If anyone attacks you, it is not from Me; whoever assails you will fall before you.

16 Behold, I have created the craftsman who fans the coals into flame and forges a weapon fit for its task; and I have created the destroyer to wreak havoc.

No weapon formed against you shall prosper, and you will refute every tongue that accuses you. This is the heritage of the servants of the LORD, and their vindication is from Me,” declares the LORD.

Do read the surrounding verses too, because the context often says more than a single verse.
