First, the prayer of King Asa:
Lord, there is no one like You to help the powerless against the mighty. Help us, O Lord our God, for we rely on you, and in Your name we have come against this vast army. O Lord, You are our God; do not let man prevail against You. -- 2 Chronicles 14:11And this, from Shakespeare's Henry V, Henry's final line before the battle of Agincourt:
... Now, soldiers, march away: And how Thou pleasest, God, dispose the day!UPDATE: Now we know -- in that Shakespearean scenario, we are the French.
