2 Chronicles 25:7-8

7But there came a man of 1God to him, saying, O king, let not the host of Israel go with thee; for Jehovah is not with Israel, [with] all the children of Ephraim.

8But if thou wilt go, do [it]; be strong for the battle: 2God will make thee fall before the enemy, for there is with 3God power to help and to cast down.
