'Deadly' in the Bible

You therefore, son of man, prophesy, and strike your hands together; and let the sword be doubled the third time, the sword of the deadly wounded: it is the sword of the great one who is deadly wounded, which enters into their rooms.

You, deadly wounded wicked one, the prince of Israel, whose day is come, in the time of the iniquity of the end,

while they see for you false visions, while they divine lies to you, to lay you on the necks of the wicked who are deadly wounded, whose day is come in the time of the iniquity of the end.

I will strengthen the arms of the king of Babylon, and put my sword in his hand: but I will break the arms of Pharaoh, and he shall groan before him with the groanings of a deadly wounded man.
