God Speaking through Pagans

2 Chronicles 35:20-24 After all this, when Josiah had prepared the temple, Neco king of Egypt went up to fight against Carchemish by the Euphrates: and Josiah went out against him. But he sent ambassadors to him, saying, “What have I to do with you, you king of Judah? I come not against you today, but against the house with which I have war. God has commanded me to make haste. Beware that it is God who is with me, that he not destroy you.”
Nevertheless Josiah would not turn his face from him, but disguised himself, that he might fight with him, and didn’t listen to the words of Neco from the mouth of God, and came to fight in the valley of Megiddo. The archers shot at king Josiah; and the king said to his servants, “Take me away, because I am seriously wounded!”
So his servants took him out of the chariot, and put him in the second chariot that he had, and brought him to Jerusalem; and he died, and was buried in the tombs of his fathers. All Judah and Jerusalem mourned for Josiah.
