God Fought the Battle

[Esther]

I'm trying to remember the scriptures where God fought the battle.

For example:

When the Israelites crossed the Red Sea and God closed the sea and drowned the Egyptian army.

And which battle was it that the army fought themselves thinking it was the enemy? Was that Gideon's battle?

Another where it sounded like horse hoofs coming, I'm thinking that was the lepers that found the camp empty.

I know God stood still the sun so the battle could be finished.

Which ones do you remember?
