1 Kings 11:26-27
11:26 Jeroboam son of Nebat, one of Solomon’s servants, rebelled against the king. He was an Ephraimite from Zeredah whose mother was a widow named Zeruah.
11:27 This is what prompted him to rebel against the king: Solomon built a terrace and he closed up a gap in the wall of the city of his father David.
