'Sharpened' in the Bible

So all [the men of] Israel went down to the Philistines, each to get his plowshare, pick, axe, or sickle sharpened.

“Son of man, prophesy and say, ‘Thus says the Lord.’ Say,‘A sword, a sword [from Babylon] is sharpenedAnd also polished!

‘It is sharpened to make a slaughter,Polished to flash and glimmer like lightning!’Shall we then rejoice [when such a disaster approaches]? But it rejects and views with contempt the scepter of My son [Judah].

The sword [of Babylon] is ready to be polished so that it may be handled and put to use; the sword is sharpened and polished to be put in the hand of the slayer (Nebuchadnezzar).

so that hearts may melt, and many will fall at their gates. I have given the glittering sword. Ah! It is made [to flash] like lightning; it is pointed and sharpened for slaughter.
