'Fought' in the Bible

"The day following, he appeared to them as they fought, and urged them to be at peace again, saying, 'Sirs, you are brothers. Why do you wrong one another?'

If I fought with animals at Ephesus for human purposes, what does it profit me? If the dead are not raised, then "let us eat and drink, for tomorrow we die."

I have fought the good fight. I have finished the course. I have kept the faith.
