'Sharpened' in the Bible

They have sharpened their tongues like a serpent. Viper's poison is under their lips. Selah.

Son of man, prophesy, and say, Thus says Yahweh: Say, A sword, a sword, it is sharpened, and also furbished;

it is sharpened that it may make a slaughter; it is furbished that it may be as lightning: shall we then make mirth? the rod of my son, it condemns every tree.

It is given to be furbished, that it may be handled: the sword, it is sharpened, yes, it is furbished, to give it into the hand of the killer.
