'Sharp' in the Bible

Your arrows are sharp;The peoples (nations) fall under You;Your arrows pierce the hearts of the King’s enemies.

Your tongue devises destruction,Like a sharp razor, working deceitfully.

My life is among lions;I must lie among those who breathe out fire—The sons of men whose teeth are spears and arrows,And their tongue a sharp sword.

When my heart was embitteredAnd I was pierced within [as with the fang of an adder],

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