Daniel Boone - Season 5 Episode 17 -

Josh's late uncle, who wanted him to give up his carefree ways, leaves him an inheritance--a plot of land near Boonesborough and an educated slave named Jonah. Josh, who doesn't believe in slavery, frees Jonah but he refuses to leave until he's made a proper gentleman out of Josh. Needless to say, Jonah's plow is in the hard ground especially when Josh enters him into a prizefight without asking.
