Ezekiel 21:11

And thou, son of man, groan with the breaking of thy loins; thou shalt even groan heavily in their sight.

And he hath given it to be furbished, that it may be handled: this sword is sharpened, and it is furbished, to give it into the hand of the slayer.

It is given to be polished, that it may be handled. The sword is sharpened. Yes, it is polished to give it into the hand of the killer.”’
