2 Chronicles 14:9-13

9Now Zerah the Ethiopian (Cushite) came out against Judah with an army of a million men and three hundred chariots, and he came as far as Mareshah.

10Then Asa went out against him, and they drew up in battle formation in the Valley of Zephathah at Mareshah.

11Asa called out to the Lord his God, saying, “O Lord, there is no one besides You to help in the battle between the powerful and the weak; so help us, O Lord our God, for we trust in and rely on You, and in Your name we have come against this multitude. O Lord, You are our God; let not man prevail against You.”

12So the Lord struck the Ethiopians [with defeat] before Asa and Judah, and the Ethiopians fled.

13Asa and the people who were with him pursued them as far as Gerar; and so many Ethiopians fell that none of them were found alive; for they were destroyed before the Lord and His army. And they carried away a very large amount of spoil.
