'Deadly' in the Bible

Their tongues are deadly arrows—they speak deception.With his moutha man speaks peaceably with his friend,but inwardly he sets up an ambush.

They will die from deadly diseases. They will not be mourned or buried but will be like manure on the face of the earth. They will be finished off by sword and famine. Their corpses will become food for the birds of the sky and for the wild animals of the land.

Therefore, hand their children over to famine,and pour the sword’s power on them.Let their wives become childless and widowed,their husbands slain by deadly disease,their young men struck down by the sword in battle.

But You, Lord, knowall their deadly plots against me.Do not wipe out their guilt;do not blot out their sin before You.Let them be forced to stumble before You;deal with them in the time of Your anger.
