'Sharpened' in the Bible

'Son of man, prophesy, and thou hast said, Thus said Jehovah, say: A sword, a sword is sharpened, and also polished.

So as to slaughter a slaughter it is sharpened. So as to have brightness it is polished, Desire hath rejoiced the sceptre of my son, It is despising every tree.

And he giveth it for polishing, For laying hold of by the hand. It is sharpened -- the sword -- and polished, To give it into the hand of a slayer.
