2 Chronicles 13:12

And, behold, God himself is with us for our Captain
To go before our armies, and fight our battles for us:

and his priests with sounding trumpets to cry alarm against you;
which was one use of the trumpets, that the people might be remembered by the Lord, and saved from their enemies, ( Numbers 10:9 ) , so that this circumstance was against Jeroboam and his army, and for Abijah and his:

O children of Israel, fight ye not against the Lord God of your
fathers;
for fighting against his people, that retained the pure worship of him, was fighting against him:

for you shall not prosper;
he seems to be assured of victory.
