Jamieson, Fausset and Brown on 2 Chronicles 14:11-13

11-13. Asa cried unto the Lord his God--Strong in the confidence that the power of God was able to give the victory equally with few as with many, the pious king marched with a comparatively small force to encounter the formidable host of marauders at his southern frontier. Committing his cause to God, he engaged in the conflict--completely routed the enemy, and succeeded in obtaining, as the reward of his victory, a rich booty in treasure and cattle from the tents of this pastoral horde.
