II Chronicles 14:8-12

And Asa had an army of three hundred thousand from Judah who carried shields and spears, and from Benjamin two hundred and eighty thousand men who carried shields and drew bows; all these were mighty men of valor. Then Zerah the Ethiopian came out against them with an army of a million men and three hundred chariots, and he came to Mareshah. So Asa went out against him, and they set the troops in battle array in the Valley of Zephathah at Mareshah. And Asa cried out to the LORD his God, and said, “LORD, it is nothing for You to help, whether with many or with those who have no power; help us, O LORD our God, for we rest on You, and in Your name we go against this multitude. O LORD, You are our God; do not let man prevail against You!” So the LORD struck the Ethiopians before Asa and Judah, and the Ethiopians fled.
