1 Kings 11:26-30

Then Jeroboam the son of Nebat, an Ephraimite of Zeredah, Solomon’s servant, whose mother’s name was Zeruah, a widow, also rebelled against the king.

Now this was the reason why he rebelled against the king: Solomon built the Millo, and closed up the breach of the city of his father David.

Now the man Jeroboam was a valiant warrior, and when Solomon saw that the young man was industrious, he appointed him over all the forced labor of the house of Joseph.

And it came about at that time, when Jeroboam went out of Jerusalem, that the prophet Ahijah the Shilonite found him on the road. Now Ahijah had clothed himself with a new cloak; and both of them were alone in the field.

Then Ahijah took hold of the new cloak which was on him and tore it into twelve pieces.
