'Ill' in the Bible

Right at that time, Jeroboam's son Abijah became ill,

Meanwhile, the LORD had spoken to Ahijah, "Be on your guard! Jeroboam's wife is coming to ask you about her son, because he is ill. You're to say such and such to her. When she arrives, she will pretend to be someone else!"

Sometime later, the son of the woman who owned the house became ill. In fact, his illness became so severe that he died.
