'Battle' in the Bible

Just as no one has power over the wind to restrain it, so no one has power over the day of his death. Just as no one can be discharged during the battle, so wickedness cannot rescue the wicked.

Again, I observed this on the earth: the race is not always won by the swiftest, the battle is not always won by the strongest; prosperity does not always belong to those who are the wisest, wealth does not always belong to those who are the most discerning, nor does success always come to those with the most knowledge -- for time and chance may overcome them all.
