'Sharp' in the Bible

Your arrows are sharp;The peoples fall under You;Your arrows are in the heart of the King’s enemies.

Your tongue devises destruction,Like a sharp razor, O worker of deceit.

My soul is among lions;I must lie among those who breathe forth fire,Even the sons of men, whose teeth are spears and arrowsAnd their tongue a sharp sword.

Sharp arrows of the warrior,With the burning coals of the broom tree.
