Why does Mr covey whip frederick chapter 10-11

He was given the task of taken an unbroken team of oxen to get a load of firewood, but the stubbornness of the creatures led to two near-death experiences for the young Douglass. Covey would listen to none of his explanations, however, and told Douglass he would show him how "to trifle away my time, and break gates." Douglass tried to refuse but to no avail, and was whipped several times for minor offenses over the next few months. Just submit your questions one at a time.
