"treated us cruelly" or "forced us to work very hard". God's warning to Solomon came true. In spite of his famous wealth, Solomon had over-taxed his own people and forced them to work for free. When the people requested that King Rehoboam reduce taxes and forced labor, he said that he would be harsher than his father. This caused the 10 northern tribes to revolt and appoint Jeroboam as their king. These northern tribes are now called the kingdom of Israel. Only Judah and Benjamin stayed with Rehoboam. They are called Judah.
