'Whet' in the Bible

If I whet my glittering sword, And my hand take hold on judgment; I will render vengeance to mine adversaries, And will recompense them that hate me.

If a man turn not, he will whet his sword; He hath bent his bow, and made it ready.

Who have whet their tongue like a sword, And have aimed their arrows, even bitter words,

If the iron be blunt, and one do not whet the edge, then must he put to more strength: but wisdom is profitable to direct.
