'Battle' in the Bible

There is no man ruling over the spirit to restrain the spirit, and there is no authority over the day of death, and there is no discharge in battle, and wickedness delivereth not its possessors.

I have turned so as to see under the sun, that not to the swift is the race, nor to the mighty the battle, nor even to the wise bread, nor even to the intelligent wealth, nor even to the skilful grace, for time and chance happen with them all.
