2 Chronicles 14:9-13

9And there came out against them Zerah the Ethiopian with an army of a thousand thousand, and three hundred chariots; and he came unto Mareshah.

10Then Asa went out to meet him, and they set the battle in array in the valley of Zephathah at Mareshah.

11And Asa cried unto the LORD his God, and said, LORD, there is none beside thee to help, between the mighty and him that hath no strength: help us, O LORD our God; for we rely on thee, and in thy name are we come against this multitude. O LORD, thou art our God; let not man prevail against thee;

12So the LORD smote the Ethiopians before Asa, and before Judah; and the Ethiopians fled.

13And Asa and the people that were with him pursued them unto Gerar: and there fell of the Ethiopians so many that they could not recover themselves; for they were destroyed before the LORD, and before his host; and they carried away very much booty.
