2 Chronicles 35:21 in the King James Version
But he sent ambassadors to him, saying, What have I to do with thee, thou king of Judah? I come not against thee this day, but against the house wherewith I have war: for God commanded me to make haste: forbear thee from meddling with God, who is with me, that he destroy thee not.
Context
20 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.
21 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.”
22 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.
