Nevertheless, Josiah would not turn his face from him
 Or withdraw his forces, and go back: 
 but disguised himself that he might fight with him;
 without being personally known, and aimed at, see ( 1 Kings 22:30 ) 
 and hearkened not unto the words of Necho from the mouth of God:
 not believing that what he said came from the Lord, though it might; and his infirmity was, that he did not inquire of the Lord about it: 
 and came to fight in the valley of Megiddo;
 which was in the tribe of Manasseh, thought to be the Magdolum of Herodotus, where he says Necho fought the battle F26; (See Gill on 2 Kings 23:29).
