And Asa and the people that were with him pursued them unto Gerar: and the Ethiopians were overthrown, that they could not recover themselves; for they were destroyed before the LORD, and before his host; and they carried away very much spoil.
Asa and his allies chased the enemies to a place called Gerar. The Ethiopians lost and couldn't recover because they were defeated by God and His forces. As a result, Asa's group took a lot of loot from them.
