2 Chronicles 13:12
“And, behold, God himself is with us for our captain, and his priests with sounding trumpets to cry alarm against you. O children of Israel, fight ye not against the Lord God of your fathers; for ye shall not prosper.”
But as for us, the Lord is our God, and we have not forsaken him; and the priests, which minister unto the Lord, are the sons of Aaron, and the Levites wait upon their business:
And they burn unto the Lord every morning and every evening burnt sacrifices and sweet incense: the shewbread also set they in order upon the pure table; and the candlestick of gold with the lamps thereof, to burn every evening: for we keep the charge of the Lord our God; but ye have forsaken him.
And, behold, God himself is with us for our captain, and his priests with sounding trumpets to cry alarm against you. O children of Israel, fight ye not against the Lord God of your fathers; for ye shall not prosper.
But Jeroboam caused an ambushment to come about behind them: so they were before Judah, and the ambushment was behind them.
