(13) But Jeroboam caused . . .--Now Jeroboam had brought the ambush round, in order to attack (literally, approach) them in the rear (literally, from behind them; so they (Jeroboam and his main body) were in front of Judah, and the ambush was in their rear.

The ambush.--The troops which Jeroboam had detached for that service.

Verses 13-16. - These verses purport to tell how Jeroboam, with all his vastly preponderating numbers (ver. 3), left nothing undone to secure the victory, and resorted even to the ambushment described; how, on the other hand, Abijah and his people honoured God by their cry and confident shout, and were delivered because they trusted in him (1 Samuel 17:45-47), and as follows, ver. 18, "relied upon the Lord God of their fathers."

13:1-22 Abijah overcomes Jeroboam. - Jeroboam and his people, by apostacy and idolatry, merited the severe punishment Abijah was permitted to execute upon them. It appears from the character of Abijah, 1Ki 15:3, that he was not himself truly religious, yet he encouraged himself from the religion of his people. It is common for those that deny the power of godliness, to boast of the form of it. Many that have little religion themselves, value it in others. But it was true that there were numbers of pious worshippers in Judah, and that theirs was the more righteous cause. In their distress, when danger was on every side, which way should they look for deliverance unless upward? It is an unspeakable comfort, that our way thither is always open. They cried unto the Lord. Earnest prayer is crying. To the cry of prayer they added the shout of faith, and became more than conquerors. Jeroboam escaped the sword of Abijah, but God struck him; there is no escaping his sword.But Jeroboam caused an ambushment to come about behind them,.... 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.
