2 Chronicles - Chapter 11

"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.  But the Lord said to Shemaiah, the man of God, “Say to Rehoboam son of Solomon, king of Judah, and to all the Israelites in Judah and Benjamin: ‘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."

The people following Rehoboam were ready to fight for their King.  But God told them to put away their swords, as what was happening was controlled by God.

The same thing happened on the night of Jesus' arrest:

"Then the others grabbed Jesus and arrested him. But one of the men with Jesus pulled out his sword and struck the high priest’s slave, slashing off his ear. “Put away your sword,” Jesus told him. “Those who use the sword will die by the sword. Don’t you realize that I could ask my Father for thousands of angels to protect us, and he would send them instantly? But if I did, how would the Scriptures be fulfilled that describe what must happen now?”"
