2 Chronicles 13:13

But Jeroboam caused an ambushment to come about behind them,
&c.] While Abijah was making his oration, he detached a party from his army, which got about, and lay in ambush, behind the army of Abijah:

so they were before Judah;
Jeroboam and the greater part of his army:

and the ambushment was behind them;
which Jeroboam had sent thither.
