Isaiah 49:2 English Standard Version
He made my mouth like a sharp sword;
in the shadow of his hand he hid me;
he made me a polished arrow;
in his quiver he hid me away.
Revelation 19:15
15 From his mouth comes a sharp sword with which to strike down the nations, and he will rule them with a rod of iron. He will tread the winepress of the fury of the wrath of God the Almighty.
