'Fatal' in the Bible

But I have not run away from being Your shepherd,and I have not longed for the fatal day.You know my words were spoken in Your presence.

“Son of man, I am about to take the delight of your eyes away from you with a fatal blow. But you must not lament or weep or let your tears flow.

One of his heads appeared to be fatally wounded, but his fatal wound was healed. The whole earth was amazed and followed the beast.

He exercises all the authority of the first beast on his behalf and compels the earth and those who live on it to worship the first beast, whose fatal wound was healed.
