'Sickness' in the Bible

Ahaziah fell down through the lattice in his upper room that was in Samaria, and was sick. So he sent messengers, and said to them, "Go, inquire of Baal Zebub, the god of Ekron, whether I will recover of this sickness."

The king said to Hazael, "Take a present in your hand, and go, meet the man of God, and inquire of Yahweh by him, saying, 'Will I recover from this sickness?'"

So Hazael went to meet him, and took a present with him, even of every good thing of Damascus, forty camels' burden, and came and stood before him, and said, "Your son Benhadad king of Syria has sent me to you, saying, 'Will I recover from this sickness?'"

Now Elisha was fallen sick of his sickness of which he died: and Joash the king of Israel came down to him, and wept over him, and said, "My father, my father, the chariots of Israel and its horsemen!"
