“Jeroboam son of Nebat, an Ephraimite of Zeredah, a servant of Solomon, whose mother’s name was Zeruah, a widow, rebelled against the king. The following was the reason he rebelled against the king. Solomon built the Millo, and closed up the gap in the wall of the city of David his father. The man Jeroboam was very able. When Solomon saw that the young man was industrious he put him in charge over all the forced labor of the house of Joseph.”
Jeroboam would lead a rebellion against Solomon now and after Solomon’s death. Jeroboam was a very able man who helped to build the Millo or fortress around the city of David. King Solomon put him in charge of the forced labor in the house of Joseph. Apparently there were Israelite slaves also as opposed to what was reported in chapter 9.
