2 Chronicles 14:8-12

Now Asa had an army of three hundred thousand from Judah, carrying large shields and spears, and 280,000 from Benjamin, carrying shields and wielding bows; all of them were valiant warriors.

Now Zerah the Ethiopian went out against them with an army of a million men and three hundred chariots, and he came to Mareshah.

So Asa went out to meet him, and they drew up in battle formation in the Valley of Zephathah at Mareshah.

Then Asa called to the Lord his God and said, “Lord, there is no one besides You to help in the battle between the powerful and those who have no strength; help us, Lord our God, for we trust in You, and in Your name have come against this multitude. Lord, You are our God; do not let man prevail against You.”

So the Lord routed the Ethiopians before Asa and before Judah, and the Ethiopians fled.
