What does 1 Kings 12:24 mean?

This is what God says: Don’t go to war against your relatives, the people of Israel. Everyone should go home, because I made this happen. So they listened to what God said and went home, just like he told them. 1 Kings 12:24 - Modern Text Bible

(God makes it clear that the split is his doing, not just a political accident. The people obey and avoid a civil war.)
