'Sharpened' in the Bible

"Son of man, prophesy, and you must say, 'Thus says the Lord,' say, 'A sword, a sword [is] sharpened and [is] also polished.

It is sharpened to slaughter a slaughter, {polished to flash like lightning}! Or will we rejoice? A rod, my son, [is] despising every tree.

And he gives it to be polished, {to be seized by the hand}. It is sharpened--a sword--and it [is] polished to give it into [the] hand of [the] killer.
