1KI 20:28

28 And there came an Ish HaElohim, and spoke unto Melech Yisroel, and said, Thus saith Hashem, Because Aram have said, Hashem is Elohei Harim, but not Elohei Amakim [(G-d of Valleys)] therefore will I deliver all this hamon hagadol [(vast multitude)] into thine yad, and ye shall know that I am Hashem.
