Earlier Elisha offered healing to Naaman, a commander in the enemies’ army, and refused to accept any reward for doing this.
Naaman would not have sought Elisha’s help if it had not been for the captured Israelite girl who suggested this solution.

The burden of its supplication was, that an ever-merciful and benignant Father of us all would watch over our noble young soldiers, and aid, comfort, and encourage them in their patriotic work; bless them, shield them in the day of battle and the hour of peril, bear them in His mighty hand, make them strong and confident, invincible in the bloody onset; help them crush the foe, grant to them and to their flag and country imperishable honor and glory —An aged stranger entered and moved with slow and noiseless step up the main aisle, his eyes fixed upon the minister, his long body clothed in a robe that reached to his feet, his head bare, his white hair descending in a frothy cataract to his shoulders, his seamy face unnaturally pale, pale even to ghastliness.
Throughout the prophets’ writings we see a call to live in a peaceable kingdom, one known for justice and mercy.
This is God’s intent for nations, an intention God again demonstrated with the coming of Jesus.
A king will form a standing army and draft their children into it.
He will collect taxes and make the people his slaves.
