111 When Rehoboam arrived at Jerusalem, he mobilized the men of Judah and Benjamin-180,000 select troops-to fight against Israel and to restore the kingdom to himself. 2 But the Lord said to Shemaiah, the man of God, 3 "Say to Rehoboam son of Solomon, king of Judah, and to all the Israelites in Judah and Benjamin: 4 'This is what the Lord says: Do not fight against your relatives. Go back home, for what has happened is my doing!'" So they obeyed the message of the Lord and did not fight against Jeroboam.

Commentary on 2 Chronicles 11:1-12
(Read 2 Chronicles 11:1-12)
A few good words might have prevented the rebellion of Rehoboam's subjects; but all the force of his kingdom cannot bring them back. And it is in vain to contend with the purpose of God, when it is made known to us. Even those who are destitute of true faith, will at times pay some regard to the word of God, and be kept by it from wrong actions, to which they are prone by nature.
