2 Chronicles 14:9-11

14:9 Zerah the Cushite marched against them with an army of 1,000,000 men and 300 chariots. He arrived at Mareshah, 14:10 and Asa went out to oppose him. They deployed for battle in the Valley of Zephathah near Mareshah.

14:11 Asa prayed to the Lord his God: “O Lord, there is no one but you who can help the weak when they are vastly outnumbered. Help us, O Lord our God, for we rely on you and have marched on your behalf against this huge army. O Lord our God, don’t let men prevail against you!”
