Chronicles II 20

15 and he said, Hear ye, all Juda, and the dwellers in Jerusalem, and king Josaphat: Thus saith the Lord to you, even you, Fear not, neither be alarmed, before all this great multitude; for the battle is not yours, but God’s. 16 To-morrow go ye down against them: behold, they come up by the ascent of Assis, and ye shall find them at the extremity of the river of the wilderness of Jeriel. 17 It is not for you to fight: understand these things, and see the deliverance of the Lord with you, Juda and Jerusalem: fear not, neither be afraid to go forth to-morrow to meet them; and the Lord shall be with you.
