For knighthode is not in the feates of warre,
As for to fight in quarell right or wronge,
But in a cause which trouth can not defarre;
He ought him selfe for to make sure and stronge
Justice to kepe mixt with mercy amonge;
And no quarell a knight ought to take,
But for a trouth or for the comins sake.
Variants
for the comins (i.e. "common's") sake — some editors give for a woman's sake
