What does 1 Kings 11:26-40 mean?

Jeroboam the son of Nebat, an Ephraimite of Zeredah, a servant of Solomon, whose mother’s name was Zeruah, a widow, also lifted up his hand against the king. And this was the reason why he lifted up his hand against the king. Solomon built the Millo, and closed up the breach of the city of David his father. The man Jeroboam was very able, and when Solomon saw that the young man was industrious he gave him charge over all the forced labor of the house of Joseph. And at that time, when Jeroboam went out of Jerusalem, the prophet Ahijah the Shilonite found him on the road. Now Ahijah had dressed himself in a new garment, and the two of them were alone in the open country. Then Ahijah laid hold of the new garment that was on him, and tore it into twelve pieces. And he said to Jeroboam, “Take for yourself ten pieces, for thus says the LORD, the God of Israel, ‘Behold, I am about to tear the kingdom from the hand of Solomon and will give you ten tribes (but he shall have one tribe, for the sake of my servant David and for the sake of Jerusalem, the city that I have chosen out of all the tribes of Israel), because they have forsaken me and worshiped Ashtoreth the goddess of the Sidonians, Chemosh the god of Moab, and Milcom the god of the Ammonites, and they have not walked in my ways, doing what is right in my sight and keeping my statutes and my rules, as David his father did. Nevertheless, I will not take the whole kingdom out of his hand, but I will make him ruler all the days of his life, for the sake of David my servant whom I chose, who kept my commandments and my statutes. But I will take the kingdom out of his son’s hand and will give it to you, ten tribes. Yet to his son I will give one tribe, that David my servant may always have a lamp before me in Jerusalem, the city where I have chosen to put my name. And I will take you, and you shall reign over all that your soul desires, and you shall be king over Israel. And if you will listen to all that I command you, and will walk in my ways, and do what is right in my eyes by keeping my statutes and my commandments, as David my servant did, I will be with you and will build you a sure house, as I built for David, and I will give Israel to you. And I will afflict the offspring of David because of this, but not forever.’” Solomon sought therefore to kill Jeroboam. But Jeroboam arose and fled into Egypt, to Shishak king of Egypt, and was in Egypt until the death of Solomon.
