“Then Jeroboam’s wife got up and went away. She came to Tirzah. As she came to the threshold of the house, the child died. All Israel buried him and mourned for him, according to the word of Yahweh, which he spoke by his servant Ahijah the prophet.”
Everything happened the way that Ahijah had said. As soon as Jeroboam’s wife stepped on the threshold of her house, the child died. All Israel mourned and buried him. Tirzah had been an ancient Canaanite city that was among the long list that Joshua conquered in Joshua, chapter 12. Somehow the power shifted from Shechem, where the great meeting took place in chapter 12, to Tirzah where Jeroboam lived.
