'Terminal' in the Bible

Now Elisha had a terminal illness. King Joash of Israel went down to visit him. He wept before him and said, "My father, my father! The chariot and horsemen of Israel!"

In those days Hezekiah was stricken with a terminal illness. The prophet Isaiah son of Amoz visited him and told him, "This is what the Lord says, 'Give your household instructions, for you are about to die; you will not get well.'"
