'Ill' in the Bible

And in the thirty-ninth year of his reign, he fell {severely} ill in his feet. But even in his illness he did not seek Yahweh, but [only] among the healers.

so he returned to Jezreel to recover from the wounds they inflicted on him in Ramoth-gilead when he fought against Aram’s King Hazael. Then Judah’s King Ahaziah son of Jehoram went down to Jezreel to visit Joram son of Ahab since Joram was ill.

When they left Joash (for they left him very ill), his own servants conspired against him because of the blood of the son of Jehoiada the priest, and they murdered him on his bed. So he died, and they buried him in the City of David, but they did not bury him in the tombs of the kings.

During this time Hezekiah became critically ill, and he prayed to the LORD. The LORD spoke to him and gave him a sign.
