Rehoboam in Jerusalem
1 When Rehoboam arrived in Jerusalem, 11:1–4 1Kg 12:21–24 he mobilized the house of Judah and Benjamin — one hundred eighty thousand fit young soldiers — to fight against Israel to restore the reign to Rehoboam. 2 But the word of the Lord came to Shemaiah, 11:2 2Ch 12:5–7,15 the man of God: 3 "Say to Rehoboam son of Solomon, king of Judah, to all Israel in Judah and Benjamin, and to the rest of the people, 4 ‘This is what the Lord says: You are not to march up and fight against your brothers. 11:4 2Ch 28:8–11 Each of you return home, for this incident has come from me.’ " 11:4 2Ch 10:15
So they listened to what the Lord said and turned back from going against Jeroboam.
