2 Chronicles 14:9-13King James Version (KJV)
9 And there came out against them Zerah the Ethiopian with an host of a thousand thousand, and three hundred chariots; and came unto Mareshah.
10 Then Asa went out against him, and they set the battle in array in the valley of Zephathah at Mareshah.
11 And Asa cried unto the Lord his God, and said, Lord, it is nothing with thee to help, whether with many, or with them that have no power: help us, O Lord our God; for we rest on thee, and in thy name we go against this multitude. O Lord, thou art our God; let no man prevail against thee.
12 So the Lord smote the Ethiopians before Asa, and before Judah; and the Ethiopians fled.
13 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.
