'Death wound' in the Bible

Now when Ahaziah, king of Judah, saw this, he went in flight by the way of the garden house. And Jehu came after him and said, Put him to death in the same way; and they gave him a death-wound in his carriage, on the slope up to Gur, by Ibleam; and he went in flight to Megiddo, where death came to him.

And I saw one of his heads as if it had been given a death-wound; and his death-wound was made well: and all the earth was wondering at the beast.

And he makes use of all the authority of the first beast before his eyes. And he makes the earth and those who are in it give worship to the first beast, whose death-wound was made well.
