'Sharpened' in the Bible

"Son of man, prophesy and say: 'This is what the Lord says: "'A sword, a sword is sharpened, and also polished.

It is sharpened for slaughter, it is polished to flash like lightning! "'Should we rejoice in the scepter of my son? No! The sword despises every tree!

"'He gave it to be polished, to be grasped in the hand -- the sword is sharpened, it is polished -- giving it into the hand of the executioner.
