History of the Peloponnesian War

——Whatever troops shall be in the king's country in consequence of the king's having sent for them, the king shall pay their expenses.——Should any of the states which have concluded this convention with the king proceed against the king's country, the rest shall prevent it, and assist the king to the utmost of their power. And should any of those in the king's country, or in all his dominions, proceed against the country of the Lacedaemonians, or of their allies, the king shall prevent it, and assist them to the utmost of his power.
