2 Chronicles 14:9-12

9And there came out against them Zerah the Ethiopian with an host of a thousand thousand, and three hundred chariots; and came unto Mareshah. 10Then Asa went out against 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, 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 not man prevail against thee.1 12So the Lord smote the Ethiopians before Asa, and before Judah; and the Ethiopians fled.
